KD*P Pockels Cells
Low voltage, large aperture Q-switching devices
The KD*P Pockels cell is a laser modulation component based on the electro-optic effect of the DKDP crystal.The products can be divided into transverse and longitudinal types based on the direction of the electro-optical effect.
The transverse type KD*P Pockels cell operates with the direction of light propagation perpendicular to the electric field. We can control the number and size of electro-optical crystals, which can effectively reduce the operating voltage to the hundred-volt level and realize the MHz repetition frequency.
The longitudinal type products operate with the direction of light propagation parallel to the electric field. CASTECH's team has developed longitudinal KD*P Pockels cell with excellent optical uniformity, high extinction ratio and high transmittance.
Applications:
●Q-switching
●Regenerative amplifier
●Cavity dumping
●Beam chopper
●Pulse picker
●Optical power stabilizer
CASTECH's products are produced independently throughout the entire process and can be customized according to customer needs. Refer to the following list for standard products.
