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.

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.
LBO Crystal

LBO (Lithium Triborate – LiB3O5) is now the most popularly used material for Second Harmonic Generation (SHG) of 1064nm high power lasers (as a substitute to KTP) and Sum Frequency Generation (SFG) of 1064nm laser source to achieve UV light at 355nm.
