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.
