What is A YAG laser?

A YAG laser is a type of solid state laser that utilizes yttrium aluminum garnet as a lasing medium. Crystalline YAG is generally doped with around 1% neodymium to replace a small fraction of yttrium ions and to provide better lasing activity. YAG lasers are one of the more common types of laser. YAG lasers can be optically pumped with laser diodes or flashtubes, and can by operated in continuous or pulsed modes—pulsed YAG laser media generally contains significantly more neodymium dopant that continuous YAG media. They typically emit light within a 1064 nm wavelength, though some transitions do occur near 940, 1120, 1320, and 1440 nm. Output powers of up to 250 megawatts have been achieved with YAG lasers.

YAG Laser Marking

YAG lasers can be used to add permanent markings and/or engravings to metal and plastic parts. The lasers' power density is carefully adjusted d
