Q-switch Nd:yag laser machine

Principle of treatment

Treatment principle for pigmented dermatosis of Q-switched Nd:yag laser therapy system lies in selective photothermolysis with melanin as the chromophore.

Q-switch Nd:yag has higher peak power and nanoseconds-level pulse width. Melanin in melanophore and cuticle formed cells have a short hot relaxation time. It could immediately make small selectively energy absorbed granules (tattoo pigment and melanin) blast without injuring surrounded normal tissues. The blasted pigment granules will be excreted from body through circulatory system.
