Characteristics of lasers:
Laser light has three main characteristics that distinguish it from other optical sources.
1- (Collimated):
Means that the light is going parallel to one direction with very little deviation even for a long distance so there is little loss of capacity along the beam. The laser pack is a thousand times brighter than daylight and more bright than the sun.
2- (Monochromatic):
It consists of one color or one wavelength so the laser pack is very pure. In contrast to the white light of the light of the lamps, it includes the spontaneous emission of photons in different wavelengths and colors going in different directions and so the light is widespread.
3- (Cohorent):
Means all waves of light moving parallel in both space and time. The normal light field of the lamp consists of a combination of radiant wavelengths in different directions and outside the sphere and so is termed the term "Incoherent".
Laser working methods:
This depends mainly on photon absorption by the chromophore or target tissue such as melanin pigment, water or hemoglobin.
