Abstract

Continuous-wave generation is demonstrated of the anti-Stokes Raman laser in new ∧ scheme ArII 3d′ 2G9/2 → 4p′ 2F7/2 → 4s′2 D5/2 with long-lived start and final levels. Red pump radiation with wavelength λp = 611 nm from a dye laser that excites transition 3d′2G9/2 → 4p′ 2 F7/2 is converted into the blue radiation at λ = 461 nm (4p′ 2 F7/2 → 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 ω is found to depend linearly on the frequency ωP of the pump field: ω ≃ ωP λP /λ. 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.
