BBO

BBO is the electro-optic material of choice for high average power Pockels cell applications at the wavelength range from 200nm to 2500nm. BBO has a high damage threshold and a low dielectric constant and is useful in high repetetion rate, high average power (up to 150W) diode pumped solid state lasers (DPSS lasers). BBO has significant advantages over other materials in terms of laser power handling abilities, temperature stability, and substantial freedom from piezoelectric ringing. Because it relies on the electro optic effect, switching time — aided by the low capacitance of the Pockels cell — is very fast. The wide transparency range of BBO allows it to be used in diverse applications

Because of crystal symmetry and the desire for the light beam to experience no birefringence in the absence of an electric field, BBO Pockels cells are transverse-field devices. It has electro-optic coefficients g₁₁=2.7pm/V andg_22,g₃₁<0.1 g₁₁. It can be used for Q-Switching a cw diode pumped Nd:YAG laser with average power>50W.

CLaser provides high quality BBO crystals with Z-cut, AR-coating and Au-electrodes for high power application.
