We report on the formation of Stokes and anti-Stokes sideband components extending over 20 THz about the center frequency (about 1.54 /spl mu/m) of the femtosecond pulse Cr/sup 4+/:YAG laser. One of the most interesting findings is that the coherent Stokes sideband around 1.65 Clm (13.5 THz in shift), depending on cavity dispersions, is greatly enhanced by stimulated Raman process in the Cr/sup 4+/:YAG rod, which has been observed and assigned to this laser system for the first time. The measured frequency shifts for all sidebands are well explained by four-wave mixing (FWM) coupled with stimulated Raman process in the laser rod, accompanied by the resonance effect of the soliton and dispersive wave (SDR) in the soliton-like modelocked laser.
