DKDP (KD2PO4) Pockels cells, also referred to as potassium deuterium phosphate pocket cells or DKDP pocket cells, are Pockels cells tool with exceptional overall performance. DKDP crystals have a low optical loss, high termination ratio, great electro-optical properties, and also excellent resistance to the environment, and so on. They can be used in electro-optical Q-switches, high-speed camera buttons, military, and air travel laser systems, and also color lasers 800 nm 2- and three-fold as well as 1064 nm two-, 3- as well as four-fold areas. Ambient temperature level range: 10 ~ 50 levels, temperature change should not surpass 5 degrees every 20 mins, ambient humidity: <40%, attempt to utilize with a humidity control device (desiccant and desiccator), when not in use, please shop in a dry box.
