Description
Introducing the KD*P Pockels Cell by CRYSTECH Inc. The KD*P Pockels Cell is a state-of-the-art electro-optical device crafted from Potassium Dideuterium Phosphate (K(H1−xDx)2PO4), commonly known as KD*P crystal. This crystal is an isomorphic form of the KDP crystal, with deuterium substitution eliminating the negative effects of infrared absorption due to hydrogen atom vibrations. This enhancement significantly boosts the electro-optical properties of the crystal, making it an ideal choice for a variety of optical applications. The higher deuterium content in the KD*P crystal not only improves its electro-optical properties but also broadens its light transmission range, offering a wide transparent band from 0.2 to 2.1 μm. The KD*P Pockels Cell leverages the longitudinal electro-optical effect of the KD*P crystal. The applied electric field is aligned with both the light transmission direction and the crystal's optical axis. This alignment allows the electric field to alter the crystal's refractive index, creating a difference between the refractive indices that is linearly related to the electric field strength. Such a configuration facilitates the creation of electro-optical switches with large apertures and high extinction ratios, making the KD*P Pockels Cell an excellent choice for applications such as laser Q-switching, electro-optical modulation (both amplitude and phase modulation), and optical pulse selection. The KD*P Pockels Cell stands out with its high electro-optical coefficients, high damage threshold, and exceptional crystal uniformity. These attributes ensure that the device performs reliably under demanding conditions, providing consistent and precise control over light modulation. Its compact structure and low insertion loss further enhance its usability in various settings, from medical systems and the beauty industry to industrial applications and scientific research fields. With a high deuterium content of over 97%, the KD*P Pockels Cell offers an impressive extinction ratio, making it a top-tier choice for professionals seeking advanced optical solutions.
