Stabilization of the emission frequency of a high-pressure waveguide CO/sub 2/ laser with the aid of resonances of saturated absorption in /sup 192/OsO/sub 4/ molecules
The emission frequency of a high-pressure waveguide CO/sub 2/ laser was stabilized using resonances of saturated absorption of the P(14) CO/sub 2/ line in /sup 192/OsO/sub 4/. The heterodyne method was used to measure (to within 2 x 10/sup -10/) the relative frequency of a new strong resonance corresponding to the A/sub 2//sup 2/ P(46) transition from the ground state of the /sup 192/OsO/sub 4/ molecule. The measurements were made relative to a narrow resonance of /sup 192/OsO/sub 4/ located near the center of the P(14) CO/sub 2/ line profile and corresponding to a transition from an excited state. The precision of the measurements was probably limited by stray amplitude modulation resulting from misalignment of the laser resonator caused by the operation of a piezoelectric ceramic plate.
