Abstract
A new kind of spontaneous mode-splitting is predicted for resonant (near resonant) pumped molecular lasers, resulting from pump field induced Rabi splitting of the emission line-shape. General conditions are presented for the occurrence of mode-splitting in homogeneously broadened systems. Results of detailed analysis pertaining to specific mid- and far-infrared lasing transitions in NH//3 show that such effects should be observable under typical experimental conditions as oscillatory instabilities in the emission. For the case of off-resonant (Raman) emission, pump-intensity dependent unidirectional cavity mode frequency shifting is predicted. This is confirmed for a CO//2 laser pumped 12. 08 mu m laser.
