Laser crystals are typically single crystals (mono-crystalline material) which are used as gain media for solid-state lasers. In most cases, they are doped with either trivalent rare earth ions or transition metal ions. YAG is commonly used as a host material in various solid-state lasers. Rare earth elements such as neodymium and erbium can be doped into YAG as active laser ions, yielding Nd:YAG and Er:YAG laser crystals, respectively. The laser crystals from us meet the most stringent requirements with regard to polishing, wavefront distortion and high damage threshold of the dielectric coatings.

Laser Crystals and Components

Nd:YAG crystal is the most early and mature laser material adopted by R&D, medical, industrial and military customers. It is the ubiquitous presence for near-infrared solid-.



Er:YAG crystal is an excellent laser crystal which lasers at 2.94μm. This wavelength is the most readily absorbed into water and hydroxylapatite of all existing


Cr4+:YAG Crystal is an excellent crystal for passively Q-switching diode pumped-pumped Nd:YAG, Nd:YLF, Nd:YVO4Nd and Yb doped lasers at wavelength from 0.8 to 1.2 m.
