Continuous-wave generation is demonstrated of the anti- Stokes Raman laser in new (Alpha) scheme ArII 3d'2G9/2 yields 4p'2F7/2 yields 4s'2D5/2 with long- lived start and final levels. Red pump radiation with wavelength (lambda) p equals 611 nm from a dye laser that excites transition 3d'2G9/2 yields 4p'2F7/2 is converted into the blue radiation at (lambda) equals 461 nm (4p'2F7/2 yields 4s'2D5/2) with efficiency of about 30%. The tunability range spans more than +/- 10 GHz around exact resonance, which is five times as wide as the Doppler contour. The output frequency (omega) is found to depend linearly on the frequency (omega) p of the pump field: (omega) approximately equals (omega) p(lambda) p/(lambda) . A sharp peak of output power is observed in the detuning curve at the exact resonance instead of 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 derived formula offers an interpretation of the observed peak.
