| Popis: | We report characteristics of a synchronously pumped picosecond all-solid-state Raman laser based on a SrMoO4 crystal at both 887 cm−1 stretching and 327 cm−1 bending anionic group symmetric vibrations. Lasing is obtained at not only the first Stokes wavelength of 1173 nm having a usual Raman shift of 887 cm−1 from the 1063-nm pumping, but also at the additional Stokes wavelength of 1220 nm with the combined 887 cm−1 + 327 cm−1 Raman shift. The strongest 26-fold shortening of the 1220-nm Raman radiation pulse down to 1.4 ps is achieved. This is close to very short dephasing time (1 ps) of the 327 cm−1 vibrational Raman line of the SrMoO4 crystal due to self-mode-locking of the 1220-nm cascaded Stokes field under intracavity pumping by the 1173-nm fundamental Stokes field. |
