The ND-YAG laser is a laser that uses a neodymium (Nd) doped aluminum yttrium garnet (YAG) crystal. Q-switch is a method of obtaining a pulsed laser mode. With Q-switch, the laser is operated in pulsed mode. Nd-YAG offers a number of different techniques and technologies that allow 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 tattoo (endogenous) pigment deep within the skin. The connections provide easy and fast operation with infrared beam - for precise work.
