DKDP Crystals for EO Applications
Broad Wavelength Range: KD*P crystals can be used in a wide wavelength range, making them versatile for various laser applications.
High Deuteration: With a deuterium content >98%, KD*P crystals can be used up to 1.3μm, extending their applicability into the infrared region.
High Optical Uniformity: KD*P crystals can be grown with high optical uniformity, ensuring consistent performance across large apertures.
Applications: Q-Switching, Large Aperture Requirements, etc.
KD*P (Deuterated Potassium Dihydrogen Phosphate, also known as DKDP) crystals are widely used in Q-switching applications due to their exceptional properties. These crystals are particularly effective in the wavelength range from 0.25µm to approximately 1.1µm. With a higher deuterium content, the absorption edge of the material shifts further into the infrared, allowing for even broader applications.
