ABSTRACT:
An optically pumped crystalline laser that includes a small single crystal section of a polygonal cylinder; the dimensions of the crystal section and the index of refraction of the crystal and the medium surrounding the crystal are such that there is formed a dielectric resonator that is totally reflective for a small number of modes. The material of which the crystal section is composed is one that is capable of being made optically thick in thin sections. The resonator is optically pumped and the lasing radiation therein is coupled to an optical element that is placed in close proximity thereto by virtue of an evanescent field that arises from the lasing action in the resonator.
