Pockels Cells (Kdp And Kd*p)

Our organization is exporting trading and supplying Pockels Cells (KDP And KD*P) to our clients in Zhangjiakou Hebei China.

KDP & KD*P are among the most widely-used commercial NLO materials characterized by good UV transmission high damage threshold and high birefringence though their NLO coefficients are relatively low. They are usually used for doubling tripling and quadrupling of a Nd:YAG laser at the room temperature. In addition they are also excellent electro-optic crystals with high electro-optic coefficients widely used as electro-optical modulators such as Q-switches Pockels Cells etc.

Applications
Laser frequency conversion-harmonic generation for high pulse energy low repetition(<100Hz) rate lasers
Electro-optical modulation
Q-Switching crystal for Pockels cells
Electro-Optical/Q-Switching application
