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.
Axicon Lens

Axicon lens usually called a rotationally symmetric prism and is a axicon lens composed of a conical surface and a flat surface. Axicon lens is often used to generate a beam of Bessel intensity distribution or a conical non-divergent beam. When changing the collimated beam into a ring beam, the plane of the cone lens should face the collimated light source. The light beam generated by the conical lens passes through the optical axis. When the distance from the conical lens to the image increases, the diameter of the formed halo will also increase, while the thickness of the halo remains unchanged. The light beam has the characteristics of a Bessel beam, and the light intensity distribution along the beam propagation direction will not change.
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.
