Laser Grade Line Mirrors

C-lens are specifically designed for fiber optics applications such as collimator, isolator, switch, collimator array and laser assembly. Compare to other gradient index lens, C-lens have several advantages including low cost, low insertion loss in long working distance, and wide working distance range. With our experienced optical design engineers, HG OPTRONICS can also provide custom designed C-lens per customer's requirement.

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.

Plano-convex circular cylindrical lenses are useful for line imaging or uni-axial magnification in a wide range of applications. These lenses may be combined with other lenses to form complex imaging systems.

α-BBO (α-BaB2O4) is a negative uniaxial crystal which has large birefringence over a broad transparent range of 190nm to 3500nm. α-BBO is an excellent crystal especially in UV and high power applications. The physical, chemical, thermal, and optical properties of alpha-BBO crystal are similar to those of Beta-BBO. However, there is no second order nonlinear effect in alpha-BBO crystal due to the centrosymmetry in its crystal structure and thus it has no use for second order nonlinear optical processes. Instead, alpha-BBO is widely used for fabrication of polarizers, polarizing beam displacers, phase retarders, birefringent plates, and time delay compensators especially those for UV and high power lasers.

The Anamorphic prisms are used in pairs to magnify input beam size along one axis while leaving the other axis unchanged. The elliptical laser diode beams can be transferred into nearly circular.

Co2+:MgAl2O4 Cospinel is a relatively new material for passive Q-switching in lasers emitting from 1.2 to 1.6 μm, in particular, for eye-safe 1.54 μm Er:glass laser, but also works at 1.44 μm and 1.34 μm wavelengths. Spinel is a hard, stable crystal that polishes well. Cobalt substitutes readily for magnesium in the Spinel host without the need for additional charge compensation ions. High absorption cross section (3.5×10-19 cm2) permits Q-switching of Er:glass laser without intracavity focusing both with flash-lamp and diode-laser pumping. Negligible excited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10.
