Abstract: Optical frequency locking of two injection lasers was achieved with the aid of a Doppler-free absorption resonance, as the result of simultaneous interaction of radiations from two lasers with rubidium vapour inside an intracavity cell. Narrowing of the emission line width by a factor of 8 and a reduction in the frequency noise by 15 dB were achieved in a band up to 350 kHz. A nonlinear frequency pulling by a resonance of coherent population trapping in an intracavity cell was demonstrated for the first time.
