Laser Optics

Prisms are transparent optical devices which refract or reflect light. They have manifold applications in laser technology.

Laser Lenses are used to focus collimated light from laser beams in a variety of laser applications. Laser Lenses include a range of lens types including HGQ Lenses, Cylinder Lenses, or Laser Generator Lenses. Laser Lenseare designed to focus light in several different ways depending on the lens type, such as focusing down to a point,a line, or a ring. Many different lens types are available in a range of wavelengths.

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

Laser mirrors are fabricated with specialized coatings, which will offer high damage thresholds.

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.

HGO grows Ho:YLF laser crystals using Czochralski technology. Ho:YLF is a very attractive laser material, because the lifetime of the upper laser level is much longer ( ~ 14 ms) than in Ho:YAG and the emission cross sections are higher. Additionally the thermal lens in Ho:YLF is much weaker, which helps to generate diffraction limited beams even under intense end-pumping. The primary advantage of directly pumping the Ho 5I7 is that it does not have to depend on energy transfer, which lends itself to various radiative and non-radiative losses. Up-conversion losses that have deleterious effect in high-energy Q-switched lasers are eliminated.

A cylindrical lens is a lens that focuses light on a line instead of a point, like a spherical lens. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line and leaves it unaltered in the direction parallel to it (in the tangent plane). In a light sheet microscope, a cylindrical lens is placed in front of the illumination objective to create the light sheet used for imaging. Cylindrical lenses focus or expand light in one axis only. They can be used to focus light into a thin line in optical metrology, laser scanning, spectroscopic, laser diode, acousto-optic, and optical processor applications. They can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical lenses are widely used in telecom applications like WSS, 40G/100G modules and laser applications like pump laser modules
