There are so many types of laser machines available in the market for medical and industrial use. Every laser has a single specific wavelength (color). The energy or power of laser light is variable and depends on technique and parameters of use. The beam of laser light is very sharp and goes like straight line (Coherent) up to a long distance. It can be manipulated by fiber optics or surface coated special mirrors depending on energy and wavelength. Every laser has a different energetic effect like cutting, heating, burning, blasting, evaporating, breaking etc. In the case of hair removal, laser energy heat up hair shafts to damage the papilla and disable surrounding cell layers, which are responsible for hair growth.

The Properties of Laser Light

1) Monochromatic light

2) Low divergence

3) Coherent light

4) Light with high Energy / Power
