GAMDAN Optics offers large quantity z-cut BBO crystals for use in BBO Pockels Cells. BBO is a popular nonlinear optical crystal for frequency conversion. BBO has also been used as electro-optic (E-O) Q-Switch material. BBO is a good material for use as an E-O Q-Switch for Er:Glass lasers because of its low insertion losses at 1.54µm and its high laser damage threshold (5GW/cm2, 10 ns). As an added benefit, BBO does not exhibit a piezoelectric effect. All these advantages make BBO an attractive...

Nd:YVO4 crystals are widely used as laser materials for diode-pumped solid-state (DPSS) lasers to yield stable and powerful infrared lasers. Nd:YVO4 has the following features: ▪ Large, stimulated emission cross-section at lasing wavelengths. ▪ Shorter pulse widths at higher repetition rates at 1.064µm and at 1.3µm. ▪ High absorption over a wide pumping wavelength bandwidth. ▪ Low dependency on pumping wavelength. ▪ Natural birefringence which typically makes strain-induced depolarization...

The lattice parameter of our crystals is well controlled and the surface polish finishing is of the highest quality, allowing a perfect epitaxy. We can provide unique pieces as well as thousands of wafers. * Diameters up to 4" (100mm). * Special configurations and shapes (squares, rectangles, etc..) are available on request. * Substrates polished surface is of high quality and ready for epitaxy.

Epolight 5838 is a narrowband absorber that is suitable for thermoplastic processing. The dye is well suited for absorbing a 532nm YAG laser. The dye has very high scotopic transmission and provides a pink lens color in the final product.

Epolight 7276A is a Visible Opaque Dye that is suitable for thermoplastic compounding. The Dye is ideally suited for use with a 910nm LiDAR system and serves to improve the signal to noise ratio by blocking interference in the Visible and IR space while allowing the LiDAR IR signal to transmit through.

AuSn pre-deposited substrates use electroplating and PVD technology for metal pattern and AuSn thin-film deposition. Thermal resistance and thermal stress are designed and matched to ensure high durability and high reliability of the device. With rich experience in the application, Focuslight can provide high stability AuSn pre-deposited substrate products and solutions in applications.

We have standard broadbands which perform well on both BK-7 and Fused Silica. V-Coatings, and double V-Coatings can be matched to a variety of substrates, as well as single layer MgF2. All can be customized by shifting to your wavelength and angle requirements.

Beta-Barium Borate (beta BBO) Crystal is an excellent nonlinear medium for Harmonic Generation (SHG,THG, 4HG, 5HG), OPO/OPG/OPA, EO-Modulation. Shalom EO's stocked and custom BBO crystals feature broad phase matching range, large SHG effective coefficients, high optical homogeneities. Our BBO are the excellent option for Nd:YAG, Femto line lasers, etc., to generate UV-IR output or gain tunable output.
