AGS(AgGaS2) crystals

AGS is transparent from 0.50 to 13.2 µm. Although its nonlinear optical coefficient is the lowest among the 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 countermeasure systems, and for SHG of CO2 laser. Thin AgGaS2 (AGS) crystal plates are popular for ultrashort pulse generation in mid IR range by difference frequency generation employing NIR wavelength pulses.
BGGSe(BaGa2GeSe6) Crystals

The BaGa2GeSe6 crystal has a high optical damage threshold (110 MW/cm2), a wide spectral transparency range (from 0.5 to 18 μm) and a high nonlinearity (d11 = 66 ± 15 pm/V) , which makes this crystal very attractive for frequency conversion of laser radiation into (or within) the mid-IR range.
AGGS(AgGaGeS4) Crystals

The AgGaGeS4 crystal is one of the solid solution crystal with extremely tremendous potential among the increasingly developed new nonlinear crystals. It inherits a high nonlinear optical coefficient(d31=15pm/V), a wide transmission range(0.5-11.5um) and low absorption coefficient(0.05cm-1 at 1064nm).
AGGSe(AgGaGe5Se12) Crystals

AgGaGe5Se12 is a promising new nonlinear optical crystal for frequency-shifting 1um solid state lasers into the mid-infrared (2-12mum) spectral range.
BIBO Crystal

BiB3O6 (BIBO) is a newly developed nonlinear optical crystal. It possesses large effective nonlinear coefficient, high damage threshold and inertness with respect to moisture. Its nonlinear coefficient is 3.5 – 4 times higher than that of LBO, 1.5 -2 times higher than that of BBO. It is a promising doubling crystal to produce blue laser.
BBO crystal

BBO is a new ultraviolet frequency doubling crystal. It is a negative uniaxial crystal, with ordinary refractive index (no) larger than extraordinary refractive index (ne). Both type I and type II phase matching can be reached by angle tuning.
