The Er:YAG laser is a solid-state laser that utilizes erbium-doped yttrium aluminum garnet as its gain medium. Known for emitting light at a wavelength of 2940 nm, it is highly effective for various applications, particularly in medical fields due to its ability to precisely ablate tissue with minimal thermal damage. This laser type is significant in both surgical procedures and cosmetic treatments, making it versatile and widely used.
