N2 - Results of experiments on the observation of frequency locking by resonant transitions of cesium vapor, a cell with which was placed in the cavity of a titanium–sapphire laser, are reported. The radiation frequency of the titanium–sapphire laser was tuned near the DII absorption line of Cs at 852 nm. In this case, simultaneous generation on the absorption line in the coherent mode locking regime and generation at the frequency specified by the spectral selector were demonstrated. Passive losses of the laser cavity at the selector frequency were less than the losses at the frequency of the Cs absorption transition. This unusual result was discussed from the viewpoint of the effect of intracavity narrow-band absorption on the emission spectra of broadband lasers and the effect of spectrum condensation.
