Neodymium-doped yttrium aluminum garnet (Nd:YAG) is a synthetic crystal used primarily as a laser medium. It is created by adding neodymium ions to a yttrium aluminum garnet matrix, which enhances its ability to emit laser light when stimulated. Nd:YAG lasers are known for their efficiency and versatility, making them popular in various applications, including medical procedures and industrial cutting. The Nd:YAG laser operates at a wavelength of 1064 nanometers, which is in the infrared spectrum. This characteristic allows it to penetrate deeper into tissues, making it effective for surgical and cosmetic treatments. Additionally, Nd:YAG lasers can be frequency-doubled to produce green light at 532 nanometers, expanding their range of uses.
