KD*P Pockels Cell
Categories:
KD*P Pockels Cell: Based on KD*P crystal (isomorphic to KDP with deuterium substitution enhancing electro-optical properties). It has high electro-optical coefficients, wide transparent band (0.2 - 2.1 μm), high damage threshold and good crystal uniformity for large-aperture and high-extinction-ratio electro-optical switches. Utilizes longitudinal electro-optical effect with applied electric field in the same direction as light transmission and crystal optical axis. Can be used as laser Q-switched electro-optical switch, electro-optical modulator (for amplitude and phase modulation), and optical pulse selector.
