the output power of lasers, especially low-gain gas lasers, depends to a large extent on the reflectivity of the laser mirrors that make up the cavity. further improvements in reflectivity can only be achieved by reducing the optical losses in the film. the absorption of the film is not only related to the extinction coefficient of the material, but also related to the distribution of the electric field strength in the film.
