摘要：

In this paper, we demonstrate the generation of three (1179, 1227, and 1323 nm) Stokes components of stimulated Raman scattering with long (925 cm(-1)) and short (332 cm(-1)) Raman shifts in an all-solid-state, synchronously pumped, extra-cavity Raman laser based on a BaWO4 crystal excited by a quasi-continuous, 36 ps, diode side-pumped Nd:GdVO4 laser generating at the wavelength of 1063 nm. We achieved the strongest 12-fold pulse shortening down to 3 ps at the 925 cm(-1) + 332 cm(-1) shifted 1227 nm wavelength due to a shorter dephasing time (wider linewidth) of the short-shift 332 cm(-1) Raman line, resulting in a peak power of 2.5 kW.
