Abstract
Continuous-wave generation of the anti-Stokes Raman laser is demonstrated in the new [Formula Presented] scheme [Formula Presented] II [Formula Presented] with quasimetastable initial and final levels. Red pump radiation with wavelength [Formula Presented] from a dye laser that excites transition [Formula Presented] is converted into the blue radiation at [Formula Presented] [Formula Presented] with efficiency of about [Formula Presented] The tunability range spans more than 20 GHz around exact resonance, which is five times broader than the Doppler contour. The output frequency [Formula Presented] is found to depend linearly on the frequency [Formula Presented] of the pump field: [Formula Presented] A sharp peak of output power is observed in the spectral profile at the exact resonance instead of the well-known two-photon dip. The model is proposed that includes ionic scattering in plasma and interaction of the running pump and standing output waves. The theory offers an interpretation of the observed peak.
