Sub-Doppler-broadened magnetic field resonances in the resonant stimulated electronic Raman scattering of multimode laser light
Animesh Sharma, W. Happer, Yukai Lu
Continuous-wave lasing without the use of any feedback mirrors is observed when atomic cesium is optically pumped to its second excited resonance state. Resonant enhancement of the lasing intensity is observed at certain magnetic fields when the atoms are pumped by multimode laser light. The resonances, with widths of only a few gauss, are shown to be due to frequency crossings in the peak gains of certain velocity groups of excited atoms.
