KD*P Pockels Cells
Product description:
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 electro-optical effect series and longitudinal electro-optical effect series.
The products of the transverse electro-optical effect series utilize the transverse electro-optical effect of DKDP crystals when the light propagation direction is perpendicular to the electric field. By controlling the number and size of the crystals, the working voltage is effectively reduced to hundreds volt level, and the repetition frequency can reach up to 1 MHz.
The longitudinal electro-optical effect series products utilize the longitudinal electro-optical effect of the DKDP crystal when the propagation direction of light is parallel to the electric field. Castech's longitudinal KD*P Pockels cell has excellent optical uniformity, high extinction ratio, and high transmittance.
CASTECH can provide a series of products with BNC connectors, as well as accessories such as polarizers, wave plates and ceramic plates, to facilitate impedance matching.
Applications:
● Q-switching ● Regenerative amplifier ● Pulse picker ● Cavity dumping
● Beam chopper ● High speed optical switch ● Optical power stabilizer
