Abstract
- The mutual interference between the transient stimulated Raman scattering and the self-phase modulation was considered a long time ago [Phys. Rev. A 2 (1970) 60]. In this work we have studied experimentally, for the first time to our knowledge, the influence of the transient stimulated Raman scattering on the self-phase modulation, considering single-shot Raman spectra. The stimulated Raman scattering was excited in methane by 140 fs pulses of the fundamental wave of a Ti:sapphire laser. Narrowing of the Stokes spectrum and suppression of the self-phase modulation structure were observed with increasing Raman gain, in agreement with the theoretical predictions. The effect has been observed up to 40 atm of methane pressure.
