BBO Pockels Cells
Product description：
BBO Pockels cell is a laser device based on electro-optic effect. When a voltage is applied to the electro-optic crystal,the refractive index of the crystal will change and the phase difference caused by the birefringence of the polarized light transmitted along the optical axis will cause the change of polarization state after exiting. The working principle of the BBO Pockels cell is based on the transverse electro-optic effect, so the working voltage can be effectively reduced by changing the size of the BBO crystal. CASTECH provides BBO Pockels cells in a range of configurations to adapt to different use conditions even unique and demanding applications. Due to its low ringing effect, repetition frequency of CASTECH's Pockels cell can go as high as 2 MHz, while by working with CASTECH' driver, its repetition frequency can reach up to 1 MHz. CASTECH also provides BBO Pockels cells with polarizers, wave plates and ceramic plates as requested.
Applications：
● Q-switching
● Regenerative amplifier
● Pulse picker
● Cavity dumping
● High speed optical switch
● Beam chopper
● Optical power stabilizer
