Advantages:
- 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.
Application:
- 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
