Wave Front Distortion Low Capacitance DKDP Pockels Cells With Compact Size
Products Description:
Potassium Dideuterium Phosphate (DKDP, KD*P) Crystal with good Electro-optical properties is most widely used in Electro-optical modulator and Q-switches, as well as in the application of Shutter for high speed photography. Besides, DKDP Crystal is applied in Second, third and fourth harmonic generation, double frequency for Nd laser and Dye laser. For DKDP and KDP Crystal have high laser damage threshold, they are used as a kind of high power laser frequency conversion materials. DKDP Crystal Electro-Optical Cells (DKDP Pockels Cells )from Crystrong has many different apertures, e.g. 5mm dia. 8mm dia. , 10mm dia. , 12mm dia. , 20mm dia. , 30mm dia. , and so on.
KDP and KD*P crystals' polished surfaces are easier to be moistened, however, the user is advised to provide a dry condition (<50%) and the sealed housing for preservation. Crystrong provides bulk supply of high quality KDP and DKDP crystals in diverse sizes for the above applications, as well as custom-made services of crystal select, design and processing.
