Q Swiched ND YAG LASER

Laser stands for ‘light amplification by stimulated emission of radiation’.

Dermatologists use lasers for various procedures. Lasers work by emitting high-intensity light with a single wavelength(with one colour )and unidirectional which target a particular tissue in the skin(called as chromophore).

The energy in the waves is absorbed by the chromophore in the skin and then destroys  it. In case of  Q switch Nd YAG  laser ,the laser beam is absorbed by unwanted  melanin pigment inside the skin cells and melanocytes in controlled manner which breaks into microfragments and then drained from the skin  by lymphatics and thereby reducing it slowly .

Q switch ND-YAG laser is one of the most commonly used lasers.
