Cr4+:YAG – Passive Q-Switch crystals
Cr⁴⁺:YAG (chromium-doped ytterbium aluminum garnet) crystals are excellent passive Q-switch crystals for Nd and Yb-doped lasers. Passive Q-switches or saturable absorbers provide high-power laser pulses without electro-optic Q-switches, thus reducing the package size and eliminating a high-voltage power supply.
Cr⁴⁺:YAG provides chemically stable, durable, UV-resistant crystals with good thermal conductivity and a high damage threshold (> 500MW/cm²). Its absorption band extends from 800nm to 1200nm and peaks at around 1060nm, with a very large absorption cross-section.
Apart from Cr⁴⁺:YAG, Altechna also offers a wide range of solid-state saturable absorbers, such as Co:MALO and V³⁺:YAG ones. All these crystals can be made in line with your needs.
