Efficient synchronously-pumped all-solid-state Raman laser at 1178 and 1227 nm on stretching and bending anionic group vibrations in a SrWO4 crystal with pulse shortening down to 1.4 ps
Original language description
We report characteristics of a synchronously pumped picosecond all-solid-state Raman laser based on a SrWO4 crystal at both stretching (nu(1) = 921 cm(-1)) and bending (nu(2) = 36 cm(-1)) anionic group symmetric vibrations. Lasing is obtained at not only the first Stokes wavelength of 1178 nm having a usual Raman shift of nu(1) from the 1063-nm pumping, but also at the additional Stokes wavelength of 1227 nm with the combined (nu(1) + nu(2)) Raman shift. The strongest 26-fold shortening of the (nu(1) + nu(2) )-shifted Raman radiation pulse down to 1.4 ps is achieved close to very short dephasing time (1.2 ps) of the nu(2) vibrational Raman mode. This is similar to the recently reported synchronously-pumped SrMoO4 Raman laser, but the output energy characteristics of the new SrWO4 Raman laser are essentially higher. At the nu(1)-shifted Raman component we have obtained the output pulse energy and slope efficiency of 40 nJ and 45%, respectively. At the (nu(1) + nu(2))-shifted Raman component these characteristics are 15 nJ and 18%, respectively, that is 5 times higher than those in the SrMoO4 laser.
