Solid state optical ring resonator and laser using same

摘要

In a monolithic optical ring resonator an optically transparent member is faceted so that the input and output beams of the resonator are coupled through a common facet at widely divergent angles in excess of 45 degrees and preferably 90 degrees. In this manner the resonator is miniaturized. The ring resonator member is contained in an evacuated housing to eliminate time-varying convective thermal detuning effects. The ring resonator is coupled in heat-exchanging relation with heating and temperature sensing film resistors deposited upon a major face of a substrate member.
