Diffusion Bonded Crystals with High Damage Threshold

The dichroic mirror is a mirror with significantly different reflection or transmission properties at two different wavelengths, it’s characterized by almost complete transmission of light at certain wavelengths and almost complete reflection of light at other wavelengths. It can be widely used in Laser technology applications.

Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8–12 um wavelength band.

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

Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. HG OPTRONICS  can provide the size from Φ1～Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to customers upon request.

Plano-concave rectangular cylindrical lenses provide uni- axial negative imaging for anamorphic beam expansion and a wide range of applications.These lenses may also be used as mirror blanks if a concave cylindrical surface mirror is required.

HGO grows Pr:YLF laser crystals using Czochralski technology. Pr3+:YLF has been found as promising laser material for producing visible lasers directly and UV lasers through intracavity second-harmonic generation. Very few laser materials have the necessary properties for the realization of lasing in the visible spectral range. Trivalent praseodymium (Pr3+) is known to be an interesting laser ion for use with solid-state lasers in the visible spectral range because of its energy levels scheme, providing several transitions in the red (640 nm, 3P0 to 3F2), orange (607 nm, 3P0 to 3H6), green (523 nm, 3P0 to 3H5), and dark red (720 nm, 3P0 3F3+3F4) spectral regions.

HG Optronics.,INC. can provide Metal Coated Mirror，Dielectric Coated Mirror and Dichroic Mirror which are made of substrate such as BK7, Optical glass, Fused Silica, CaF2 and so on.  

Potassium Gadolinium Tungstate (KGd(WO₄)₂) crystal is an excellent stimulated Raman laser crystal with characteristics such as a wide light transmission range, good thermal conductivity, high damage threshold, large Raman shift coefficient, and high Raman gain. It can maintain high conversion efficiency and beam quality during the Raman frequency conversion process. The KGW crystal can withstand high pump power and is suitable for pump lights of various wavelengths, making it widely used in Raman lasers, laser frequency conversion, medical imaging, photodynamic therapy, environmental monitoring, spectroscopy research, material processing, and other fields.
