Laser therapy uses coherent, monochromatic light – part of the segment of visible light or microwaves. The laser beam is the carrier of energy, which it can deliver after falling on the illuminated plane. The Helium-Neon laser applies the red light with the wavelenght 632.8 nm. The diode-based therapeutic laser have the wavelenght from 532 nm (green) up to 1060 nm (infrared). In order to affect the superficial tissues it is better to use laser with a shorter wavelenght, infrared laser affect deeper layers. The laser can be applied either continuously or in impulses.

It has a significant biostimulating effect, mainly due to the fact that it stimulates collagen, support tissues vascularisation, speeds up the regeneration of blood vessels, lymphatic routes and epithelia, better use of oxygen and glucose, and in general facilitates the healing process. At the same time it acts as anagesic, anti-inflammatory agent (Antibacterial and antiviral agents), and causes also the shrinking of oedemas. However the application of laserhas olso several conterindicatins (strict prohibition of application on eyes, on maling and precancer tissues, banned application on glands, belly during pregnancy, varicose veins or acute neuralgic attacks). Application is done locally, based on the doctor´s prescription, either on small areas (aglic points,initiating trigger points, treatment of wounds, etc.), or larger areas (using laser-scanner).
