2940nm laser

Principles of 2940nm Erbium Laser Laser stands for “Light Amplification by Stimulated Emission of Radiation.” The Erbium laser (Er:YAG laser) is a solid-state laser that uses erbium-doped yttrium aluminum garnet (Er:YAG) as its gain medium. It primarily emits light at a 2940nm wavelength, which belongs to the mid-infrared spectrum and has a high absorption rate […]
