King of infrared nonlinear crystals with large nonlinear coefficient (d36=75pm/V), wide transparency (0.75–12μm), high thermal conductivity, and laser damage threshold. Ideal for high-power mid-IR OPO/OPA systems.
High-performance UV frequency doubling crystal. Negative uniaxial with excellent phase matching tunability. Used in SHG, THG, and ultrafast laser systems.
Low absorption, wide transparency range, and high damage threshold make LBO ideal for high-power frequency conversion in UV and visible regions.
High nonlinear coefficient and excellent thermal stability. Widely used in SHG of Nd:YAG lasers and OPO applications.
Transparent from 0.50 to 13.2 µm. Used in OPOs pumped by Nd:YAG, Ti:Sapphire, and CO2 lasers. Ideal for mid-IR generation via DFG.
Mid-IR nonlinear crystal with wide bandgap (3.54 eV), high damage threshold, and no two-photon absorption at 1μm. Suitable for fs laser pumping.
Efficient diode-pumped laser material with broad absorption and emission bands. Used in high-power thin-disk and slab lasers.
Passive Q-switch for Nd:YAG, Nd:YVO4, and other 1μm lasers. High damage threshold and excellent thermal stability.
High transmission in 0.5–20 μm range. Ideal for CO2 laser optics, thermal imaging, and spectroscopy.
Converts Gaussian beam into ring-shaped Bessel-like beam. Used in medical, industrial, and scientific applications.
All crystals are grown using horizontal and vertical methods, ensuring high homogeneity, low absorption, and excellent optical performance.
