Cr4+:YAG (Y3Al5O12) crystal is ideal for passive Q-switch operation of Nd:YAG and other Nd3+ or Yb3+ doped laser crystals in the wavelength range of 900 nm to 1200 nm. Passive Q-switches or saturable absorbers provide high power laser pulses without electro-optic Q-switches, thereby reducing the package size and eliminating a high voltage power supply. A remarkable feature of Cr4+:YAG is the high damage threshold of >10 J/cm2@1064 nm, 10 ns. Its absorption band extends from 900 nm to 1200 nm and peaks around 1060 nm with a very large absorption cross-section.

Laser Line Mirrors are used for beam-steering in demanding laser applications. Laser Line Mirrors are Optical Mirrors that have been designed for specific laser types or wavelengths.

HGO have advanced coating machines which can meet endusers’different application requirement. We can very high laser induced damaged threshold coating with IAD, EB and IBS coating techniques , also Cr-Au, Aluminum and silver mental coating can also be available in HGO. Customers are very welcome to contact with us for further information.

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.

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.

Our beamsplitter plates can be used in high power laser system. When using beamsplitter plates, it is important to make it in mind that the two partial beams travel in different optical paths. The optical paths depend on the incident angle and the thickness of plates.

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.

Nd:YAG is the earliest and most famous laser host crystal. Since it combines great advantages in many basic properties,Nd:YAG is the ubiquitous presence for near-infrared solid-state lasers and their frequency-doubler, tripler, and higher order multiplier. It is widely used in industrial, medical, military and scientific fields.. Nd:YAG crystals are wildly used in all types of solid-state laser systems-frequency-doubled continuous wave, high-energy Q-switched, and so forth.Its good fluorescent lifetime thermal conductivity and physical strengths makes it suitable for high power lamp pumped laser.
