    DHR coating can be provide very high reflection (more than 99.8% at designed wavelength).They are commonly used in a single wavelength laser cavity where the lowest cavity loss at a center wavelength is essential. Center wavelength range from 250nm to 2200nm for DHR coatings. Rising EO offer a variety of Laser quality mirror with DHR coatings.

Laser mirrors are used on the surface of solid-state lasers including alexandrite, Nd-glass,ruby, and YAG types. They are also used in conjunction with other optical elements and components, on the surfaces of other types of lasers. Laser mirrors are formed from a variety of materials and are usually coated with a multi-layer, low absorption, dielectric coating to facilitate reflectance. Some of the more common types of materials used include BK7 glass (borosilicate glass), copper, fused silica and UV grade fused silica, nickel, optical crown glass, and proprietary materials.
