Products Description
DKDP
Potassium Deuterium Phosphate (DKDP ) are among the most
widely-used commercial NLO materials. They are commonly used for
doubling, tripling and quadrupling of 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, Q-switches, and Pockels Cells, etc.
ELECTRO-OPTICAL/Q-SWITCHING APPLICATIONS
- Crystrong offers highly deuterated D>96% electro-optic crystal -
DKDP for Q-switching application;
- Standard dimensions of electro-optic DKDP crystals for Q-switching
are cylinders dia 920 mm and dia 1224 mm however manufacturing of
custom size and rectangular shape crystals is available
- Gold evaporated or silver paste electrodes are available;
- Dielectric thin film AR coatings for specified laser wavelengths
are available;
- Typical quarter wave voltage 3.4 kV at 1064 nm;
- Typical contrast ratio between crossed polarizers better than
1:2000;
- Damage threshold of AR coated DKDP surface >5 J/cm2 at 1064 nm,
10 ns pulses.
FREQUENCY CONVERSION APPLICATIONS
- DKDP crystals are used for second harmonic generation of high pulse
energy low repetition rate (<100 Hz)
Q-switched and mode-locked Nd:YAG lasers. Cut angle of crystal
Parallelism $ 20 arcsec crystal for operation at room temperature
is 36.6° for type 1 phase matching and 53.7° deg for type 2 phase
matching.
- DKDP crystals are used for third harmonic generation. Cut angle of
crystal for operation at room temperature is 59.3° for type 2 phase
matching.
- Type 1 DKDP crystals with non-critical cut angle θ=90° are used for
fourth harmonic generation (532nm→266nm) of high pulse energy
Q-switched and mode locked Nd:YAG lasers. Crystal must be heated at
-50 ℃ temperature to match NCPM conditions.
ADVANTAGES
- Good UV transmission
- High optical damage threshold
- High birefringence
- High nonlinear coefficients
APPLICATIONS
- Laser frequency conversion — harmonic generation for high pulse
energy,
- Electro-optical modulation
- Q-switching crystal for Pockels cells
