Nonlinear Crystals

Grow methods including horizontal and vertical, these materials(ZnGeP2, AgGaS2, AgGaSe2, GaSe, KTA, KTP, BIBO, LBO, BBO) are available with given standard sizes and orientations. Some of which, with properties of large nonlinear coefficient and unique dimensions we provided are widely used in regular SHG,THG and Mid-infrared OPO,OPA systems, etc. Products can be delivered with or without Anodized Aluminium holder.

BGS(BaGa₄S₇) Crystals

BaGa₄S₇(barium gallium sulfide, BGS)crystal is a mid-infrared nonlinear crystal with wide band-gap and stable chemical properties. It has a wide light transmission range, with a UV cutoff edge of 350nm (band-gap width3.54eV)and an infrared cutoff edge of 13.7um.It also has a high nonlinear coefficient and a high damage threshold. In addition, BaGa₄S₇ crystal has no two-photon absorption at lμm,and can be used for OPO pumped by1064nm Nd:YAG lasers, especially suitable for using the1030nm fs laser, which is relatively mature in the market, as a pump source to generate various nonlinear frequency conversions such as OPA, DFG, SFG, OPG, etc.
LGS (LiGaS2) Crystal

LGS is a new type of mid-infrared nonlinear crystal. LiGaS₂ has excellent properties such as wide band gap, low two-photon absorption, wide transparent range, small group velocity mismatch, high thermal conductivity, and low thermal expansion coefficient.
GaSe Crystal

Gallium Selenide (GaSe) non-linear optical single crystal, combining a large non-linear coefficient, a high damage threshold and a wide transparency range. It is a is very suitable material for SHG in the mid-IR.
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).
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.
