In 1965 Drs. Sinclair, Knoll and Master pioneered the way for therapeutic lasers. These lasers don’t cut or destroy tissue, rather stimulate and thereby provide a healing effect. The energy here is of a non-thermal light photons, which can be absorbed by the body and be converted to chemical energy and so initiate numerous balancing functions.

Unlike other light sources, laser is coherent, meaning the oscillation is in the same direction and phase. This is very beneficial as the body communicates also in the same coherent light language. By stimulating the body with an appropriate laser light of wave-length 630-980 nanometer, the body can be aided for proper oxygenation and detoxification of the cells and tissue regeneration.

Hot lasers used for medical purposes can increase the temperature of the contact surface, While cold laser (a term used for Low Level Laser Therapy or LLLT) will not raise that temperature. Cold lasers are used for tissue stimulation without having sufficient strength to cause cell damage (staring directly into the laser beam should be avoided as it could irritate the retina and damage the eye). Once the cold laser light energy enters the tissue photochemical reactions take place, which will stimulate the natural biological processes that help control the pain and initiate body’s own healing mechanisms (photons that enter the damaged cells, produce energy—ATP—improving their function, assist cell division, strengthening the immune system and the secretion of various hormones.
