DKDP Pockels Cell

DKDP Potassium Dideuterium Phosphate Pockels cell or KD*P Pockels cell is a Pockels cell device with relatively excellent comprehensive performance. Potassium diduterium phosphate DKDP (KD*P) crystal has the advantages of low optical loss, high extinction ratio, good electro-optic performance and good environmental tolerance. It uses its longitudinal effect to make an electro-optic Q-switched switch, which is suitable for pulsed solid- state lasers It is usually used in the fields of laser cosmetology and laser medical treatment under low repetition rate conditions .

Product Description

The deliquescence and mechanical properties of DKDP crystal itself are poor. When using it, please pay attention to the following operating environment: temperature operating range: 10~50 degrees, temperature change should not exceed 5 degrees every 20 minutes, ambient humidity: <40%, Try to use it with a humidity control device (drying vessel and desiccant), and store it in a dry box when not in use.

Note: Since the quarter-wave voltage and half-wave voltage required by the DKDP Pockels cell are related to temperature, at a wavelength of 1064nm, the law of the quarter-wave voltage changing with temperature is that the temperature increases by 1ºC, so A quarter-wavelength voltage rise of approximately 50V is required. That is, dV/dT is about +50V/ºC.
