Abstract
A ring laser gyroscope is provided. A light source is configured to generate light of a first wavelength. A plurality primary cavity mirrors are configured to route light of a second wavelength around a primary cavity to a readout device. One primary cavity mirror of the plurality of primary cavity mirrors includes a gain medium. The pumping mirror and the one primary cavity mirror including the gain medium is positioned and configured to reflect the light of the first wavelength back and forth in a pumping cavity through the gain medium, wherein the light of the first wavelength stimulates the gain medium to generate the light of the second wavelength that are reflected around the primary cavity to the readout device.
