Abstract : In the patent a thin layer of laser material is deposited on an appropriate substrate with a second layer of a suitable activator material such as silver or copper, for example, deposited thereover. The deposition of laser material is accomplished at as high a temperature as possible while maintaining a practicable deposition rate. The combination of layers is then baked at a high temperature in air or an inert atmosphere for several hours and slowly reduced to room temperature. The method transforms the film of laser material into a single crystal or several smaller crystallites capable of desirable laser action. In its preferred embodiment reflective coatings, anti-reflective coatings, and multi-layers may be employed to enhance the laser performance.
