Anti-reflective Coated Quartz Window KDP Pockel Cell For DPSS Nd:YAG lasers
Products Description:
KDP and DKDP is routinely used for Q-switching applications from the UV out to about 1.1 um where absorption limits its use in active cavities, although it can be useful at longer wavelengths when a few percent of absorption can be tolerated.
KD*P based Pockels cells are routinely used for Q-switching applications from the 400 nm to about 1.1um. Most of commercial flash-lamp pumped Nd:YAG lasers and low repetition rate DPSS Nd:YAG lasers are equipped with KD*P based Pockels cell for laser cavity Q-switching.
Elector-optical KD*P crystals have high laser power resistant dielectric AR coatings. Additionally some series Pockels cells have AR coated windows for improved lifetime and protection in less user friendly environment.
