Metallic mirror coatings are used to create reflective components for many applications but laser applications tend to require a higher reflectivity than those offered from standard metallic mirror coatings. Because of this, multilayer dielectric HR coatings are usually used for laser mirrors instead of metallic mirror coatings, as they can achieve higher reflectivity. Metallic surfaces reflect light because loosely attached electrons freely oscillate with incident light waves without much impedance or hindrance, but all metals will absorb some amount of incident light. This makes metallic mirror coatings susceptible to damage when used with high power lasers.1

Dielectric overcoats also improve handling of metallic mirrors, increase the durability of the metal coating, provide protection from oxidation, and enhance the reflectance of the metal coating in specific spectral regions. Metal coatings are very delicate without a protective coating and require extra care during handling and cleaning. The surface of an unprotected metal coating should never be touched or cleaned with anything other than clean, dry air. Isopropyl alcohol or acetone can be used to clean metal mirrors with a dielectric coating. Table 1 shows a list of Edmund Optics’ standard metallic mirror coating options, while Table 2 shows a list of Edmund Optics’ standard dielectric HR laser coatings.

Dielectric HR coatings reflect light based on constructive interference during Fresnel reflections and have the complete opposite purpose of AR coatings in that they utilize constructive interference to maximize Fresnel reflections instead of utilizing destructive interference to minimize them (Figure 1). The constructive interference is caused by alternating layers of high and low refractive index materials with thicknesses specifically chosen to maximize reflectivity at a given wavelength range. In a λ/4 dielectric mirror, also known as a Bragg mirror, the thickness of each layer corresponds to a quarter of the design wavelength. Layer thickness is based on the wavelength in the material, not the vacuum wavelength.2

Highly reflective (HR) coatings are used to minimize loss while reflecting lasers and other light sources. Absorption and scatter during reflection lead to decreased throughput and potential laser-induced damage. HR coatings are used in common laser optics applications such as folding a laser’s beam path and laser cavity end mirrors.
