The ND-YAG laser is a laser that uses a neodymium (Nd) doped aluminum yttrium garnet (YAG) crystal. Q-switch is a method to achieve 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 make-up and tattoos (endogenous) pigment deep in the skin. The connections ensure simple and fast operation with infrared beam - for precise work.
