Cold Laser Research Literature and Information

Laser Technology Overview
In 1917, Albert Einstein established the physical principle of “Light Amplification by Stimulated Emission of Radiation,” thus paving the way for the development of the laser. In June 1960, Theodoro H. Maiman constructed the world’s first laser using a ruby crystal, now known as the ruby laser. In 1965, doctors Sinclair, Knoll and Mester pioneered the way for therapeutic lasers through their research with human tissue. These lasers do not cut or destroy tissue, but biostimulate the tissue creating a therapeutic curative effect.
Therapeutic lasers work by supplying energy to the body in the form of non-thermal photons of light. The body is able to absorb this external energy on a cellular level and transform light energy into chemical energy, which the body uses to accelerate the normal healing rate of tissue for a wide range of ailments.

Laser Light vs. L.E.D Light

When people are introduced to laser therapy there is often confusion as to the difference between Laser light and L.E.D light. Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. A laser is referred to as a coherent beam of light. Laser light is coherent because all of the light waves stream out in the same direction and phase. If one points a laser on a surface close to them, the laser light will have a noticeable diameter. If one pulls the laser further from that surface the diameter and intensity of the light will not change.
L.E.D lights are referred to as non-coherent. In other words the light that is emitted from an L.E.D spreads out in all directions and are out of phase. If one points a L.E.D on a surface close to them, the L.E.D light will have a noticeable diameter. If one pulls the L.E.D further from that surface the diameter of the light will become larger and more diffused

Laser and the Language of the Body

The text you are reading is obviously written in English. You can read and understand these words and ether accept or reject the content. What if it were written in an unfamiliar language—Spanish, Japanese, German, Korean, or Swahili? Would you understand the content? Would you be able to make rational decisions based on what you can piece together? Like most people, probably not. This is the dilemma our bodies have when being treated by various therapies. Our bodies do not communicate in ultrasound or electrical stimulation—it communicates in coherent light. In the book, Energy Medicine: The Scientific Basis by James L. Oschman, multiple references are made to the communication within the body—from cell to cell as coherent (laser) light.
It makes sense that we should stimulate the body with the same language that the cells in the body communicate. That is why there is so much success with wound healing, neurological rehabilitation, and illness reversal when using LLLT.

Measuring Light

Light occurs in wavelengths and is measured in nanometers. A nanometer (nm) is one billionth of a meter,
which can be represented by scientific notation as 10-9 meters or .000000001 meter = 1nm. The visible
spectrum of light occurs in range of 380 – 760nm. Below 380nm we have ultraviolet light and above 760nm we have infrared light. Although all levels of light can have biological effect, most laser research suggests that the most advantageous levels of stimulation for healing purposes on a superficial level down 1/4-1/2 inch occur in the 630 – 660nm range. The biological effects that have been measured in this range have been proper oxygenation and detoxification of the cell, absorption by the mitochondria of photons (which are converted into ATP), DNA replication, and regeneration of damaged nerve tissue. In the 760-905nm near infrared laser range deeper penetration and delivery of photonic energy and cellular metabolism occur, along with cellular absorption of photons down to the hard tissue level (1-3" with continuous or pulsed laser from 5-7" with superpulsed laser), along with activation of endorphins and beneficial enzymes plus deactivation of inflammation causing enzymes.

Tune in on Laser Communication

—such as 102.7 KIIS FM. Similarly, when
purchasing a laser, you must first choose a wavelength of light. Most lasers on the market used by professionals are in the red or infrared range. It is safer to use a red (630-650nm) laser over an area for a longer period of time without worry of damaging tissue or over stimulating. This makes it ideal for an unattended therapy. When working with infrared (760nm or higher) lasers more caution should be taken with treatment so as to not over-treat. The nice thing about the infrared lasers is that you can usually get them in more powerful diodes up to 500 mW each. More power equals faster treatment times for the patient, and efficient use of the practitioners time.

Pump up the Volume

The output of a laser is measured in Watts (or more acurately MiliWatts). It is easier to understand output as the volume of the laser. For example: when the Beatles’ song, “We All Live in a Yellow Submarine,” is playing on the radio, one can raise or lower the volume without affecting the message of the song. One can lower the output/volume of the song, “we all live in a yellow submarine,” and it occurs as a faint whisper possibly inaudible. Or one can blast the song, “WE ALL LIVE IN A YELLOW SUBMARINE,” and damage our eardrums. Regardless of the output/volume the message remains the same. The same occurs with laser. The output will not change the laser wavelength (i.e. 650nm); it will only determine the intensity.

Cold Laser

Cold Laser is the common term used for a Low Level Laser Therapy (LLLT) device. It is considered cold laser
because it will not increase the thermal temperature of what it is contacting. Cold lasers deliver power from 1mW to 500mW. Anything over 500mW has the potential of generating heat. When dealing with cold laser therapy, the
output is well below one Watt of energy, usually measured in milliwatts (mW). In scientific notation this is
represented as 10-3 or .001Watts = 1mW. Although very few people can actually feel a laser with this output, the positive biological effects are amazing. A wide range of professionals use cold laser therapy with success including chiropractors, physical therapists, medical doctors, naturopathic doctors, osteopaths, acupuncturists, veterinarians, dentists, sports therapists, and massage therapists. The common goal among these practitioners is accelerated healing time and improved results for their patients.

Hot Laser

Most lasers used by medical professionals on the market are “HOT” lasers or high powered lasers. Hot lasers are lasers that have an output larger than one Watt (1000mW) and the ability to increase the temperature of what it is contacting—Ouch! Hot lasers are used for a variety of procedures from cutting and cauterizing tissue, removing tarter from teeth, hair removal, and even eye surgery. Not to be confused with Cold Lasers as defined above.

Results are Rapid and Sustainable

While some patients get immediate results, others usually require three to six treatments before they notice a lasting effect. Again, each patient will respond differently according to his or her own body’s natural healing rate. Although it is recommended that you come in daily for the first three visits, following this two to three times per week is usually sufficient to maintain your cells in biostimulation. Your clinician is best able to develop a schedule tailored specifically to your condition.

There are three main components of tissue that affect the absorption of light specifically: water, hemoglobin (pigment that renders blood red) and melanin (pigment that gives skin its natural color.) The absorption curves for these three substances versus the laser wavelength will determine the precise impact that a particular laser will have on tissue. This laser light has the unique properties of monochromaticity, (a single wavelength,) coherence (travels in a straight line) and defined location (concentrated beam). These properties are what allow lasers to penetrate the skin surface, non-invasively, delivering energy directly to the cells, which the cells then convert into chemical energy.

True Lasers versus Super-luminous Diodes
True lasers such as the Quantum System focus all of their energy in one direction in a very concentrated line. A super-luminous diode, on the other hand, diffuses its energy in all directions with only a small percentage of the energy traveling in the direction of the treatment. A true laser system will deliver 90% more power to the treatment area than a super-luminous diode system.

Oshiro’s Studies Confirm This Fact:
“A laser beam travels only in one direction from its source, unlike a light bulb. The resulting (true laser) beam has a considerably higher photo density than a monochromatic beam produced by filtering and collimating a conventional multi-wavelength light source. In in-vivo tissue targets, several layers of non-homogenous particulate matter have to be penetrated before the beam can reach the LLLT targets and it is the superior photon density of coherent light which ensures this penetration; even though actual coherence may be lost in the first few cell layers.”
Generally speaking, LLLT is remarkable in the fact that it safely and effectively reduces inflammation, relieves pain, and heals tissues. In healing tissues, the mechanism increases the synthesis of collagen—the same matrix found in cartilage. As the synthesis of collagen is increased, the cartilage begins to rebuild.
The fact that therapeutic lasers work by supplying energy to the body in the form of photons of light and
allowing the body to effect its own repairs allows therapeutic lasers the ability to treat an extensive list of
ailments. Ailments that involve skin, tendons, nerves, blood vessels or muscles can be treated with therapeutic lasers.

Reasons That Using Low-Level Laser Therapy
Will Enhance Your Practice and Patient Results:

• Low level laser therapy causes certain photochemical reactions to occur to help control pain, reduce inflammation, and accelerate healing of damaged tissue. Low level laser therapy treats a variety of conditions including arthritis, tendon and ligament problems, nerve root irritation, shoulder and back pain, repetitive strain injuries, TMJ, plantar fasciitis, burns, wounds, and a variety of other skin conditions

• Low level laser therapy is painless and gives great clinical results with a minimum time involvement. Low level laser therapy will increase your patient compliance and satisfaction through efficient and highly effective treatment.

• You will grow your practice by providing additional proven pain management rehabilitation to your existing patient base. Many patients have claimed that the laser is what made the difference in accelerating their healing and getting them well. You will find that many returning patients specifically request to have laser therapy.

• You will attract new patients which will seek your care due to the need for therapeutic laser rehabilitation treatments. Referrals will come in from medical doctors, healthcare practitioners and coaches who know you use low-level laser therapy.

• You will set your clinic apart from the competition by providing the most modern form of therapeutic technology.

• Increase the profitability of your practice though additional billable services.


Low Level Laser Therapy (LLLT) is quickly
becoming the first line of attack in pain control
and tissue healing in rehabilitation medicine. It is
safe, painless, quick and easy to apply and
results are often immediate with no side effects.
Laser therapy has been valuable in the
treatment of a variety of conditions, including
patient suffering acute, chronic or post-operative
pain. Other conditions which have responded
well are: arthritis, osteoarthritis, tendon and
ligament problems (tendonitis), nerve root
irritations (back and neck dysfunction), shoulder
and back pain, repetitive strain injuries, TMJ,
plantar fascitis, burns, wounds and a variety of
other skin conditions.
The term laser is an acronym for Light
Amplification by Stimulated Emission of
Radiation. It is a pure form of light energy of a
specific color and wavelength, which has special
healing properties. The 635 nm frequency is the exact frequency used and created by the cells.
Low power lasers do not generate perceivable
heat. Therefore, when the laser contacts the
skin the patient experiences no warmth or
burning as a result of the laser. Although certain
nerves may be stimulated by the laser light,
most people feel nothing at all while a few may
feel a slight tingling during the treatment.
There are two general types of medical lasers:
high power lasers, which cut through tissue, and
low power lasers, which stimulate tissue repair.
This is referred to as photo-bio-stimulation.
Stimulation of tissue includes wound healing,
tissue repair, swelling reduction, increased blood
flow and pain reduction.
Treatments may last as little as 2 minutes or as
long as 20 minutes. The total number of
treatments required is usually 3-15,
depending on the body’s natural healing rate.
This will be different for each patient. The less
severe or acute the condition, the fewer number
of treatments required. The more severe of more
chronic the condition, the greater number of
treatments required.
Lasers used for tissue stimulation are called cold lasers because they don't heat tissues and they have
insufficient strength to damage cells. However,
as the laser beam is often invisible, the patient
should avoid staring directly into the beam as it
could irritate the retina and in sustained dosage
permanently damage the eye. After 30 years of
clinical use, low power lasers have not been
found to have any adverse effects or cause
cancer. In fact, lasers are proving useful in pain
management for chronic cancer patients.
While some patients get immediate results,
others usually require 3 to 6 treatments before
there is a lasting effect. Again, each patient will
respond differently according to his or her own
body’s natural healing rate.
When laser light interacts with tissue, it causes
certain photochemical reactions to occur and
stimulates natural biological processes. Many of
these reactions have beneficial effects on the
body which help to control pain and accelerate
Although it is recommended that patients come in
daily for the first three visits, if this is not
possible, two to three times per week is usually
sufficient to maintain the cells in biostimulation.

Laser Photons and Pharmacological Treatments in Wound Healing
Farouk A.H. Al-Watban, MSc, PhD, and Bernard L. Andres, MT(AMT) Laser Medicine Research Section,
Biological and Medical Research Department, King Faisal Specialist Hospital & Research Center,
Riyadh, Saudi Arabia.
The exploitation of photobiology in medicine has been of great interest to mankind. There is a growing interest in the use of lasers for treatment purposes because of the photochemical alterations induced in biomolecules by light energy. In this paper we present our data on laser biostimulation, the combination of pharmacological treatments SolcoserylTM (SS) and PolygenTM (PG) with light therapy using in-vitro and in-vivo models. Invitro experiments indicate the ability of laser photons and pharmacological agents SS or PG to augment or abate the cloning efficiency of various cell lines. In-vivo studies focused on the dosimetry of various laser wavelengths and the use of wound healing drugs and 632.8nm laser in wound healing. The application of pharmacological treatments combined with laser therapy reveals the utility of light-drug treatment combinations.

Given the ever-increasing cost of medical care, the burden incurred on patients, caregivers and
society, this line of research fulfills the increasing need to develop treatment methods that enhance wound
healing, especially in situations involving resistance to healing.

The Biological Effects of Laser Therapy and Other Physical Modalities on Connective Tissue Repair Processes.
Chukuka S. Enwemeka, P.T., Ph.D., FACSM, G. Kesava Reddy, Ph.D., Department of Physical Therapy and Rehabilitation Sciences, University of Kansas Medical Center, Kansas City, KS 66160-7601, USA:
Connective tissue injuries, such as tendon rupture and ligamentous strains, are common. Unlike most soft
tissues that require 7-10 days to heal, primary healing of tendons and other dense connective tissues take as much as 6 - 8 weeks during which they are inevitably protected in immobilization casts to avoid re-injury. Such long periods of immobilization impair functional rehabilitation and predispose a multitude of
complications that could be minimized if healing is quickened and the duration of cast immobilization
reduced. In separate studies, we tested the hypothesis that early function, ultrasound, 632.8 nm He-Ne laser, and 904 nm Ga-As laser, when used singly or in combination, promote healing of experimentally severed and repaired rabbit Achilles tendons as evidenced by biochemical, biomechanical, and morphological indices of healing.

Our results demonstrate that:
(1) appropriate doses of each modality, i.e., early functional activities, ultrasound, He-Ne and Ga-As laser therapy augment collagen synthesis, modulate maturation of newly synthesized collagen, and overall, enhance the biomechanical characteristics of the repaired tendons.
(2) Combinations of either of the two lasers with early function and either ultrasound or electrical stimulation further promote collagen synthesis when compared to functional activities alone. However, the biomechanical effects measured in tendons receiving the multi-therapy were similar, i.e., not better than the earlier single modality trials. Although tissue repair processes in humans may differ from that of rabbits, these findings suggest that human cases of connective tissue injuries, e.g., Achilles tendon rupture, may benefit from appropriate doses of He-Ne laser, Ga-As laser, and other therapeutic modalities, when used singly or in combination. Our recent meta-analysis of the laser therapy literature further corroborate these findings.
