Abstract

A microlaser formed from a self-doubling crystal which has two opposite dielectrically coated faces and which is positioned in close proximity to a diode laser pump source for intracavity second harmonic generation of blue light. By employing the proper doping concentrations of lasant material and pumping the gain medium which has a specific crystalline orientation, the desired efficient blue microlaser is achieved.
