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

• 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
