Q-Switched Nd Yag Laser technology has greatly improved the ability to treat melanocytic lesions and tattoos with the rapidly pulsed Q-switch.The Nd yag laser treatment of pigmented lesions and tattoos are based on principle of selected photothermolysis.
HuafeiMedical Laser Q Switch Nd Yag System delivers light of specific wavelengths in very high peak energy pulses which are absorbed by the pigment in the tattoo and result in an acoustic shock-wave. The shock-wave shatters the pigment particles, releasing them from their encapsulation and breaking them into fragments small enough for removal by the body. These tiny particles are then eliminated by the body.
Since the laser light must be absorbed by the pigment particles, the laser wavelength must be selected to match the absorption spectrum of the pigment. Q-Switched 1064nm lasers are best suited for treating dark blue and black tattoos, but Q-Switched 532nm lasers are best suitable for treating red and orange tattoos.
