Abstract

Wavefront reconstruction (WFR) in stimulated scattering was discovered by Zeldovich et al. in 1972 [1]. WFR is attributed to the intensity cross correlation among incident and backward scattered light beams in each transverse cross section of the interaction region, both in the case of stimulated Brillouin scattering (SBS) [1] and stimulated Raman scattering (SRS) [2]. The phenomenon of reconstruction of the wavefront of a light beam during SRS had also been detected experimentally by Kudryavtseva et al. [3] and Sokolovskaya et al. [4]. Till now, all the experimental investigations related to WFR via backward stimulated Raman scattering (BSRS), have been done using multimode waveguides, where the presence of a large number of modes in the transverse interaction region, results in effective WFR via stimulated scattering.
