    Notes: Abstract Stimulated electronic Raman scattering (SERS) in atomic vapours provides a simple method of extending the tuning ranges of pulsed dye lasers well into the infrared region. The special advantages of this technique in comparison with other types of tunable infrared lasers are discussed, and are illustrated by describing a SERS system which uses a modest nitrogen laser-pumped dye laser (∼ 20 kW). This produces infrared radiation tunable from 2.67 to 3.47μm by SERS in caesium vapour, which is contained in a heat pipe oven. Photon conversion efficiencies of up to 50% are obtained. The design of the heat pipe oven, operation of the system and optimization of experimental parameters are described in detail.

    Infrared stimulated Raman generation: Effects of gain focussing on threshold and tuning behaviour (1975)
    Springer
    Applied physics 8 (1975), S. 333-340

    Notes: Abstract It is shown that for generation of infrared radiation by stimulated Raman scattering, the diffraction spread of the Stokes wave can have a significant effect on the threshold. Compared with an analysis in which gain focussing is neglected, the threshold powers may be much higher with a corresponding reduction in tuning range. The design of a Raman oscillator is considerably influenced by these diffraction effects, and also it is found that the Stokes wave is subject to frequency-pulling which is dependent on the pump power.
