KD*P Pockels Cell
Categories:
The KD*P Pockels Cell utilizes the longitudinal electro-optic effect of the KD*P crystal, where the direction of the applied electric field aligns with both the light propagation direction and the crystal optical axis. The applied electric field alters the refractive index of the crystal, and the difference between the two induced refractive indices is linearly proportional to the electric field strength. KD*P Pockels Cells can be used as electro-optic Q-switches for lasers, electro-optic modulators (for amplitude and phase modulation), and optical pulse selectors.
Deuterated potassium dihydrogen phosphate ( abbreviated as KD*P ) is an isomorphic crystal of KDP. The substitution of hydrogen by deuterium eliminates the influence of infrared absorption caused by hydrogen atom vibrations and significantly enhances the electro-optic properties of the crystal. The higher the deuteration degree of the KD*P crystal, the better its electro-optic performance and the broader its transmission range. KD*P crystals feature high electro-optic coefficients, a wide transparent range (0.2 - 2.1μm), high damage threshold, and excellent crystal uniformity, enabling the fabrication of large-aperture, high-extinction-ratio electro-optic Q-Switches.
