HGO grows LBO Nonlinear crystals using flux technology. LBO crystals is an excellent nonlinear crystal.For frequency doubling(SHG),tripling(THG) of Nd:YAG,Nd:YLF,Nd:YVO4 lasers, it is one of the most useful nonlinear optical materials in ultraviolet and visible laser applications.

ZnSe is used widely for IR components, windows and lenses, and applied for Thermal Imaging, FLIR,  Medical systems and Co2 Laser Zinc Selenide (ZnSe) Windows are ideal for a wide variety of infrared applications including thermal imaging, FLIR, and medical systems.

Laser Protect Windows(Laser protective glass, protective filters or welding protective windows) are used to save for the high cost of laser optics.

Beamsplitter Penta Prism by adding a wedge and with partial reflective coating on one of its leaning surfaces, Penta Prism can be used as Beamsplitter. Transmission/reflection (T/R) ratio of 50/50, or others for Beamsplitter Penta Prism is available upon request.

Invented by H.W. Dove, Dove Prisms are also known Reversion prisms.  When the prism is rotated about its length axis, the image viewed through the prism rotates at twice the prism rotation rate.  This is an unusual and sometimes useful property for special applications. Entry and exit faces are anti-reflection coated.

Dispersion Prisms are used in applications that require separating the incident light into its component wavelengths. For example, when white light enters a Dispersion Prism, it is separated into its three components: red, green, and blue. Dispersion Prisms are ideal for spectroscopy or laser tuning.

Nd:GdVO4, is a promising material for diode pumped lasers. Similar to the more well-known Nd:YVO4 crystal, Nd:GdVO4 crystal also exhibits high gain, low threshold, and high absorption coefficients at pumping wavelengths. Nd:GdVO4 has the additional advantage over Nd:YVO4 of a much higher thermal conductivity. For CW lasing at 1.06 um and 1.34 um and intracavity doubling with KTP and LBO, the gadolinium vanadate have produced a higher slope efficiency or optical conversion than Nd:YVO4.

Nd:YVO4 (Neodymium Doped Yttrium Orthovanadate) crystals is one of the most promising commercially available diode pumped solid state laser materials, especially, for low to middle power density. This is mainly for its higher absorption and emission features than Nd:YAG crystal. Pumped by laser diodes, Nd:YVO4 crystal has been incorporated with high NLO coefficient crystals ( LBO, BBO, or KTP) to frequency-shift the output from the near infrared to green, blue, or even UV. This incorporation to construct all solid state lasers is an ideal laser tool that can cover the most widespread applications of lasers, including machining, material processing, spectroscopy, wafer inspection, light displays, medical diagnostics, laser printing, and data storage, etc. It has been shown that Nd:YVO4 based diode pumped solid state lasers are rapidly occupying the markets traditionally dominated by water-cooled ion lasers and lamp-pumped lasers, especially when compact design and single-longitudinal-mode outputs are required.
