NanoSwitch Series BBO Pockels Cells 

BBO ( BaB2O4, Barium Borate) crystal as an electro-optical material has significant advantages over other materials (e.g. KD*P and LN) in terms of laser power handling ability, temperature stability, and substantial freedom from piezoelectric ringing. It has become the  material of choice for high repetition rate, high power Pockels cells at a very wide range of wavelength from 210nm to 2100nm.
