BBO is an excellent electro-optic crystal for high power application, wavelength range from 200 to 2500nm.  It has electro-optic coefficients γ11=2.7pm/v and γ22,γ31<0.1γ11.  It launches a super Q-switch for a cw diode pumped Nd:YAG laser with average power>50W.

Red Optronics supplies a variety of large size BBO crystal with Z-cut for electro-optic application.
