DKDP Q-Switch

DKDP Q-Switch 2021-10-12T23:38:48+00:00


  • High deuteration (>98.0%) DKDP
  • Excellent electric-optical properties
  • High extinction ratio, High damage threshold
  • Low λ/4 Voltage, Single Pass Optical Transmission

DKDP crystal is the most widely-used commercial NLO material, it is usually used for doubling, tripling and quadrupling of a Nd:YAG laser under the room temperature. In addition, it is also excellent electro-optic crystals with high electro-optic coefficients, widely used as electro-optical modulators, such as Q-switches, Pockels Cells, etc.


  • SHG, THG, FHG of Nd:lasers.
  • Frequency doubling of dyer laser
  • High power laser frequency conversion materials
  • Shutter for high speed photography
  • Electro-optical modulator and Q switches
