Pockels cells alter the polarization state of incident light when applying the voltage on electro-optic crystal. When working with polarizers, these cells can function as optical switches or laser Q-switches. BBO Pockels cells is based on the transverse Pockels effect. The voltage could be reduced by changing the ratio of BBO's width to length.

Due to the low piezoelectric response and high laser damage threshold of BBO, CASTECH's BBO Pockels cells can support up to 1MHz frequency. Complete portfolio with various clear aperture and length is available.

All the Pockels cells are equipped with protective windows with high transmittance AR coating to prevent the Pockels cells from contamination and moisture so as to provide adequate assurance of the product performance and durability.
