Deuterated Potassium Dihydrogen Phosphate DKDP Crystal

Our Deuterated Potassium Dihydrogen Phosphate DKDP Crystal is well received in the market. KDP ( Potassium Dihydrogen Phosphate ) crystal and DKDP ( KD*P or Potassium Dideuterium Phosphate ) crystal feature large size with good UV transmission, high damage threshold and high birefringence, though their NLO coefficients are relatively low. They are commonly used for doubling, tripling and quadrupling of Nd laser. In addition, they are also excellent electro-optic crystals with high electro-optic coefficients, widely used as electro-optical modulators, EO Q-Switches, etc.

Infrared nonlinear AgGaSe2 Crystal

Our Infrared nonlinear AgGaSe2 Crystal products are your best choice! Infrared nonlinear AGSe2 crystals, AgGaSe2(AgGa(1-x)InxSe2) Nonlinear Crystal has band edges at 0.73 and 18 µm. Its useful transmission range (0.9–16 µm) and wide phase matching capability provide excellent potential for OPO applications when pumped by a variety of different lasers. Tuning within 2.5–12 µm has been obtained when pumping by Ho:YLF laser at 2.05 µm; as well as non-critical phase matching (NCPM) operation within 1.9–5.5 µm when pumping at 1.4–1.55 µm. AgGaSe2 (AgGaSe) has been demonstrated to be an efficient frequency doubling NLO Crystals for infrared CO2 lasers radiation.

Infrared nonlinear AgGaS2 Crystal

We have many years of experience in the production of Infrared nonlinear AgGaS2 Crystal. Infrared nonlinear crystals AGS ( AgGaS2 ) is transparent from 0.53 to 12 µm. Although its Nonlinear Optical Crystal coefficient is the lowest among the above mentioned infrared crystals, high short wavelength transparency edging at 550 nm is made use of in OPOs pumped by Nd:YAG laser; in numerous difference frequency mixing experiments with diode, Ti:Sapphire, Nd:YAG and IR dye lasers covering 3–12 µm range; in direct infrared counter measure systems, and for SHG of CO2 laser. Thin Nonlinear Optical Materials AgGaS2 (AGS) IR materials crystal plates are popular for ultrashort pulse generation in mid IR range by difference frequency generation employing NIR wavelength pulses. NLO Crystals AGS and AGSe......
