The ND-YAG laser is a laser that uses a neodymium (Nd) doped aluminum yttrium garnet (YAG) crystal. Q-switch is a method for obtaining a pulsed laser mode. With Q-switch, the laser is used in pulsed mode. Nd-YAG offers a number of different techniques and technologies that enable the use of a single laser module for the removal of all facial and body pigmentation. The most powerful single pulsed energy of 2000 mj easily and completely removes permanent makeup and tattoos (endogenous) pigment deep in the skin. The connections ensure simple and fast operation with infrared beam - for precise work.
