Laser therapy uses selected wavelengths of light to stimulate key molecules in human tissues. Decades of medical research have identified the wavelengths, energy level and frequencies that induce changes in cellular metabolism (Photobiostimulation), for instance melanin absorbing sunlight changes skins pigmentation. K-Laser delivers energy from superficial to deep tissues activating a cascade of photochemical reactions that promotes cell function, enabling treated tissues to accelerate the stages of the healing process and reduce pain sensation. This is a safe and non-invasive technique that uses the body’s own reparative processes.


Therapeutic Effects


State Of The Art Technology


1. INCREASED METABOLIC ACTIVITY. By stimulating key molecules (haemoglobin, water, cytochrome c) K-Laser therapy improves tissue oxygenation, ATP synthesis and intercellular exchanges, activating a cascade of photo-chemical reactions that speeds up the healing, regenerative process.

2. IMPROVED VASCULAR ACTIVITY. K-Laser therapy induces vasodilation in the treated area and promotes angiogenesis, thus improving blood circulation, optimising tissue nutrition and removal of cell waste and inflammatory factors. K-Laser boosts the lymphatic drainage system as well. As a result, there is a reduction in swelling caused by bruising or local inflammation.

3. ANTI-INFLAMMATION. Laser therapy accelerates the termination of the inflammatory process*. Interleukin-1, a cytokine that has immune and pro-inflammatory actions, is proven to be reduced by laser treatment, and the antioxidant Super Oxide Dismutase (SOD) levels are enhanced, helping reduce damaging free-radical activity.

4. IMPROVED NERVE FUNCTION. Laser therapy is proven to facilitate the normalisation of nerve signal transmission in the autonomic, sensory, and motor neural pathways. Both Compound Muscle Action Potential (CMAP) and Nerve Latency values show improvement following laser treatment. It is also proven to stimulate axonal sprouting and cell regeneration in damaged nerves*.

5. ANALGESIC EFFECT. Pain relief is the result of nerve activity alteration, reduced localised inflammation and swelling, proven to happen following a K-Laser therapy course*.

6. ACCELERATED TISSUE REPAIR AND CELL GROWTH. K-Laser wavelengths, power and pulse frequencies penetrate at depth into tissues and accelerate cellular reproduction and growth by increasing their metabolism. As a result, the cells of tendons, ligaments, muscles and bones are repaired faster*.

7. REDUCED FIBROUS TISSUE FORMATION. Early K-Laser Therapy can prevent the accumulation of scar tissue following tears, burns or surgery. Once healed the tissues are proven to be more elastic with minimal scarring, reducing the onset of chronic pain associated with scars.

8. IMMUNOREGULATION. Acceleration of Leukocytic activity and enhanced Lymphocytic response have been observed in treated tissues  (enhances the removal of nonviable tissue components and rapid repair). Wounds treated with the K-Laser are more resilient to secondary infections.

9. FASTER WOUND HEALING. Laser therapy optimises collagen and elastin deposition: wounds treated with the K-Laser are proven to heal faster, with increased tensile strength preventing further breakdowns. K-Laser therapy is effective on Chronic Diabetic Ulcers* and traumatic wounds.

10. ACUPUNCTURE POINTS. K-Laser therapy stimulates acupuncture points allowing needleless acupuncture.

Class IV therapeutic lasers deliver effective dosages to deeper tissues, and shorten treatment times. K-Laser is a FDA and EU safety regulated equipment allowed to be safely used as a human therapeutic biostimulatory laser. K-Laser’s Class IV diodes deliver an effective energy dose from superficial to deep tissues in an biological and economic time frame.



The wavelengths selected by K-Laser are proven to be effective and safe in laboratory and clinical studies (Research section). They are absorbed by key cellular molecules throughout the body from superficial skin to deep musculoskeletal tissues. The photobiostimulation effects produced by these wavelengths are synergistic enhancing tissue healing and pain management .

660 nm.  This wavelength is absorbed principally by the melanin in our skin, providing metabolic photobiomodulation of superficial epidermal and dermal tissues. It is the least penetrative K-Laser beam and is the only Class 3b emitted, as only a weak laser beam is required for superficial cell structure stimulation.

800 nm.  This wavelength penetrates the deepest tissues and is absorbed by the cytochrome C oxidase, the terminal enzyme in the cell's respiratory chain, which determines how efficiently the cell converts molecular oxygen into ATP - the fuel of the cell. This enzyme is highly absorptive to the 800nm wavelength, higher enzymatic action results in more ATP produced. ATP production is massively increased in the treated tissues, creating faster and more efficient cellular repair.

905 nm. This wavelength is the peak absorption of haemoglobin in the blood. Laser energy absorbed by haemoglobin alters its structure, releasing oxygen to the surrounding tissues above the normal metabolic levels and speeding up the healing process. 

970 nm. This wavelength is principally absorbed by the water in our tissues, and converted into heat energy. The temperature and pressure gradients created at cellular level stimulate improved local micro-circulation, enhancing tissue nutrition and oxygen supply, whilst taking away inflammatory markers and cellular waste. Laser therapy has been shown to promote neovascularization, with repeat regular use over time. 



Published studies have revealed that different pulse frequencies stimulate different physiological effects, potentially due to water content. For instance, low frequencies elicit an analgesic effect and stimulate bone cell growth, whereas higher frequencies promote soft tissue cellular growth and anti-inflammatory action. K-Laser can produce a vast spectrum of frequencies -  from Continuous Wave to 20.000 Hz, which progress automatically during each protocol, based on tissue type, skin pigmentation, depth, chronicity of the ailment and level of pain. For deep musculoskeletal tissue or Central nerve cell stimulation Intense Super Pulse frequencies are utilised in the protocols to ensure biological stimulation of deep tissues with minimal superficial tissue heating.


Not all lasers are equal, be sure you understand the technology behind the therapy to ensure it is fit for purpose.

Both LED (Light Emitting Diodes) and Laser Diode technologies are used as optical transmitters for various applications.

LASER DIODES (Light Amplification by the Stimulated Emission of Radiation) produces an intense beam of light energy characterised by the following physical properties:
•  Monochromatic ( meaning that the beam consists of one wavelength).
•  Coherent (meaning all parts of the beam are in phase).
•  Collimated (meaning all the photons travel in one and same direction, without dispersion in multiple directions).
None of the above apply to LEDs, which have a spectral spread from 30 to 100nm - a high dispersion. Spectral spread in Lasers is less than 1nm. This means that the therapeutic wavelengths are more precisely produced by a laser diode than by a LED system. The depth of tissue penetration is wavelength-dependent.
Laser's ON/OFF switching speed is faster than LED's, consequently the therapeutic dosage is more accurately delivered by a Laser Diode than by a LED, and the Intense Super Pulse delivery mode (essential for certain tissue types) cannot be performed by a LED system.
More importantly, LED technology have a low output intensity: this means it takes a longer time to produce a therapeutic dosage compared to Laser and produce non-coherent light that does not penetrate deep tissues.

The only way to categorise Lasers is the ANSI Classification based on power of the laser beam. Class I lasers are the weakest form, with early Class 3b lasers becoming medical devices and more recently the arrival of medical Class IV therapeutic lasers. K-Laser has a red Class 3b laser categorisation and infra-red Class IV therapeutic beams. Both Class 3b and Class IV lasers require protective goggles.

Industry, military, surgical and medical therapeutic lasers

CLASS IIIb LASERS. Evolved as therapeutic lasers in the 1960’s, after initial studies in labs on cell cultures to study the interaction between light and cells, they were the earliest medical therapeutic laser manufactured. Class 3b lasers are not allowed to produce more than 0.5 Watts, although effective on superficial structures and wounds, take a long time to produce a significant dosage for effectively treating deep musculoskeletal tissues. For example, in order to treat a chronic lumbar pain on a medium-sized patient over 150cm2, the recommended total dosage of 3220J is required: to produce that amount of energy, a Class IIIb needs 268 minutes (Time=J/W). making is difficult for a clinician to treat a patient over such a long timeframe.
The same treatment applied with a K-Laser takes only 4.5 minutes, making the treatment biologically effective and economic to the clinician and patient.

Some manufactures of Class IIIb lasers claim that Class IV ones are too powerful and may burn the patients. This claim is scientifically invalid and has only marketing purposes. The K-Laser is FDA and CE approved and has undergone the most rigorous safety tests required by the British, European and FDA legislation.


For most therapeutic lasers, few basic parameters fit all the applications. The outcome of the therapy is based on set standard protocols (i.e. set wavelength, power and pulse frequency) rather than precision condition or tissue treatments. The K-Laser is different to other lasers.

Every tissue type is stimulated by a specific combination of K-Laser Light parameters, depending on its skin pigmentation, body size, tissue type, chronicity of damage, levels of pain and water contents, depth of penetration.

TISSUE TYPES. Most conditions affect more than one tissue type. K-Laser protocols are composed by various phases, each phase delivering a different combination of parameters in order to stimulate every tissue type and metabolic process affected by the condition.

BODY SIZE. Different body sizes require different dosages. K-Laser allows you to tailor the dosage down to the size of each patient.

PAIN CHRONICITY. Recent studies on Laser Therapy have revealed that certain parameters are more effective on chronic pain and others on acute pain. K-Laser allows one to refine the treatment according to the chronicity of your patient's injury.

SKIN COLOR. The human skin absorbs and reacts to light in different ways depending on its pigmentation. A dark skin tone absorbs light more than a caucasian one. The K-Laser alter its protocol parameters’ based on the colour of the patient’s skin. This guarantees safety as well as effectiveness.

BODY PART. Every body part is composed of various different tissues. The pre-sets in the K-Laser are calibrated to take these different cell lines into account, and deliver the correct combination of parameters for the target body part.

The innovative K-Laser software recombines its parameters based on your inputs, producing for you the optimal dosage and delivery modality for the patient you are about to treat.  K-Laser: personalised treatments tailored on the individual. As the clinician becomes more confident with laser medicine and K-Laser itself, new protocols can be created and stored to suit their clients’ specific requirements.
