Cr:YAG
Cr:YAG
Cr4+:YAG is an excellent crystal for passivel Q-Switching 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 µm. Because of its chemical stability, durability, UV resistance, good thermal conductivity, high damage threshold(>500MW/cm) and easy operation, it will replace some traditional switching materials, such as, LiF, organic Dye and color centers.
