Product Specification / Models

Cr:YAG Crystal

Passive Q-Switching is preferred for simplicity of manufacturing and operation, low cost and reduced system size and weight. Cr4+:YAG is an excellent crystal for passively Q-switched diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Yb:YAG or other Nd and Yb doped lasers at wavelength from 1.0 to 1.2 mm. Because of its chemical stability, durability, UV resistance, good thermal conductivity, high damage threshold (> 500 MW/cm2) and easy operation, it will replace some traditional switching materials, such as, LiF, organic Dye and color centers.

Nd:YAG Crystal

Nd:YAG is still the important solid laser material with the most excellent comprehensive properties up to now.The non-core and nondislocation Nd:YAG was granted the first prize in the National Quality Competition.
