Four-photon resonant parametric sum-frequency generation using coherent and noise pumping in potassium vapor

Andrey V Aleksandrov, Vladimir S Solomatin

An experimental investigation was made of the use of noise pumping in four-photon resonant parametric sum-frequency generation in potassium vapor. A two-photon resonance with the 9S1/2 and 7D3/2,5/2 levels and a one-photon resonance with the 10P1/2,3/2 and 11P1/2,3/2 levels were used. A comparison was made with the case of coherent pumping and it was found that, under conditions of strong dispersion and wave mismatch, the efficiency of the process using noise pumping differs negligibly from the efficiency using coherent pumping although the spectral density of the coherent pump is substantially higher than that of the noise pump.An experimental investigation was made of the use of noise pumping in four-photon resonant parametric sum-frequency generation in potassium vapor.

Spatial evolution of wave amplitudes, stability of solutions, and bifurcations in sum and difference frequency generation processes under two-photon resonance conditions

Nikolai E. Kornienko

An investigation is made of four-photon sum and difference frequency generation under two-photon resonance conditions allowing for population migration accompanying incoherent processes and for the possibility of a one-photon quasiresonance with the emitted radiation in inverted and uninverted media. A study is made of parametric bleaching of the medium and phase locking of the interacting waves, their stability, and influence on the conversion quantum efficiency η . It is established that resonant parametric processes have a larger region of stability than nonresonant ones. An analysis is made of bifurcation, typical of resonant processes, that strongly influences η . Accurate analytic expressions are derived for the maximum attainable values of η and it is shown that there is an optimum frequency detuning from a one-photon resonance.An investigation is made of four-photon sum and difference frequency generation under two-photon resonance conditions allowing for population migration accompanying incoherent processes and for the possibility of a one-photon quasiresonance with the emitted radiation in inverted and uninverted media.

Spectral properties of resonant four-photon parametric oscillation

G. M. Barykinsky, Vladimir V. Lebedev, V M Plyasulya

An investigation was made of the spectral properties of four-photon parametric oscillation when the frequency of the generated field is tunable near an atomic resonance line. An ω4 = ω1–ω2+ω3 generation process involving coherent anti-Stokes scattering in thallium vapor was achieved experimentally. Biharmonic pumping was provided by resonant excitation of a 6P1/2–6P3/2 two-photon transition at the frequency ω1–ω2. Measurements were made of the oscillation power when the frequency ω3 was tunable near the frequency of a 6P3/2–7D3/2 transition at various thallium vapor pressures. It was found that the spectral properties of resonant parametric oscillation depend strongly on the concentration of active-mixture atoms and also on various saturation effects.An investigation was made of the spectral properties of four-photon parametric oscillation when the frequency of the generated field is tunable near an atomic resonance line.
