Abstract

The optical elements that define the resonant cavity in a laser must meet exacting standards of optical performance. Not only must the reflectance and transmittance be tailored to fit the gain characteristics of the laser cavity, but the absorption and scatter losses in the coatings must be limited to prevent degradation of laser performance. Current requirements for laser optics are diverse. Mirrors for tunable dye lasers must meet broadband requirements for reflectance and transmittance. In ion lasers, wavelength selection using cavity mirrors with narrow bandwidth characteristics has become practical. Laser isotope separation and free electron lasers have stimulated needs for optics with wavelength discrimination characteristics and extremely low absorption loss. This paper will discuss both generic requirements and specific coating types in the 240nm to 10 um spectral regime. A number of special cases where optical coatings provide unique solu-tions for evolving requirements will also be examined.
