Potassium Dihydrogen Phosphate (KDP) and Potassium Deuterium Phosphate (KD*P) 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.

In the nonlinear optical crystal, BBO crystal is a kind of crystal with obvious comprehensive advantages and good performance. It has a very wide light transmission range, a large matching angle, a high resistance to light damage threshold, and a broadband temperature matching. Excellent optical uniformity, especially for the triple frequency of Nd:YAG lasers.

Periodically poled lithium niobate (PPLN) is a highly efficient crystal for nonlinear wavelength conversion processes, which has a wide light transmission range and covers the NIR and MIR spectral regions, PPLN is used for SHG、SFG、OPO, and other nonlinear processes from Visible to MIR. In order to meet the requirements of modern optics for diverse laser wavelengths. the output of any wavelength in the transmittance range can be realized through the design of periodic structure.

​DLATGS crystal is a crystalline material with a pyroelectric effect, which can provide a wide range of infrared radiation from the near-ultraviolet (NUV) light edge of 0.4 μm (~750 THz) to the far-infrared spectrum of 200 μm (~1.5 THz). It has a wide range of uses in aerospace, military, medical, and fire safety fields.
