Nd:YAG lasers are solid-state lasers that use neodymium as the dopant in a yttrium aluminum garnet crystal. They emit light at a wavelength of 1064 nanometers, which is in the infrared spectrum. These lasers are known for their high efficiency and ability to produce powerful beams, making them suitable for various applications, including industrial cutting, welding, and medical procedures. In addition to their industrial uses, Nd:YAG lasers are also employed in cosmetic treatments, such as tattoo removal and skin resurfacing. Their versatility and effectiveness have made them a popular choice in both medical and aesthetic fields, providing precise and controlled energy delivery.
