Wide-band high-reflectivity interference coatings for laser pumping systems

Wide-band interference reflectors for laser pumping systems are considered. Calculations and measurements are reported of multilayer interference coatings with a high reflectivity in the spectral range of the absorption of ruby and of neodymium-activated media. The results are given of experimental investigations of the character!sties of lasers with pumping-system reflectors coated with high-reflectivity interference films.
