The Nd:YAG laser is a solid-state laser that uses neodymium ions doped in a yttrium aluminum garnet crystal as its gain medium. It emits light at a wavelength of 1064 nanometers, which is in the infrared spectrum. This type of laser is known for its high efficiency and ability to produce powerful beams, making it suitable for various applications, including medical procedures and industrial cutting. In medical settings, the Nd:YAG laser is often used for procedures like laser surgery, tattoo removal, and skin resurfacing. Its ability to penetrate deep into tissues while minimizing damage to surrounding areas makes it a valuable tool in dermatology and ophthalmology. Additionally, it is utilized in manufacturing for cutting and welding materials.
