Am. Akulshin et M. Otsu, INJECTION-LASER FREQUENCY PULLING BY INTR ADOPPLER ABSORPTION RESONANCES IN INTRACAVITY CELL, Kvantovaa elektronika, 21(7), 1994, pp. 613-614
An optical trapping is realized of two diode laser frequencies by intr
doppler absorption resonance, which is due to two laser radiation inte
raction with rubidium vapours in intra cavity cell. Oscillation line n
arrowing by the factor of 8 is obtained, as well as frequency noise re
duction by 15 dB in 350 kHz band. For the first time nonlinear frequen
cy pulling by resonance of coherent capture is shown in the intracavit
y cell.
