Abstract In two previous papers [8, 9] a theory has been developed for the phenomenon of selflocking in a pressure broadened three mode He-Ne laser. Using this phenomenon, a new method of measuring the frequency stability of another laser is presented. Actual measurements of the frequency stability of a 633 nm single frequency He-Ne laser by means of this new method are reported. The design and construction of the single frequency laser is described briefly. Using an intracavity quartz etalon, multimode to single mode output power conversion efficiencies as high as 92% have been observed in the range of several mW. Continuous tuning over a frequency range of 1.2 GHz is achieved by a combination of etalon tilting and resonator length variation. A frequency stability better than 1∶108 over periods of several min has been realized.
