Efficient synchronously-pumped all-solid-state SrWO4 Raman laser at 1178 and 1227 nm on single and combined Raman modes with 26-fold pulse shortening down to 1.4 ps

Popis výsledku v původním jazyce

In this paper, the characteristics of synchronously pumped picosecond Raman laser based on the 36 mm long SrWO4 crystal at the shifts of nu(1) = 921 cm(-1) and nu(2) = 336 cm(-1) under 36-ps extracavity pumping are presented. The first Stokes at the wavelength of 1178 nm, corresponding to the Raman shift of nu(1), with the slope efficiency of 45.1%, output energy of up to 40 nJ, and pulse duration of 33 ps, respectively, was achieved for the output coupler reflectivity of 89%. In the case of setup with the higher cavity Q-factor at 1178 nm, we obtained not only usual nu(1)- shifted Raman radiation at 1178 nm, but also the unusual line at the wavelength of 1227 nm (nu(1) + nu(2)). This additional line was achieved with the slope efficiency of 18.1 % and the output energy of 15 nJ with the output coupler reflectivity of 96.5% at 1227 nm. Strong pulse shortening from 36 ps down to 1.4 ps at the wavelength of 1227 nm was observed at +50 mu m positive detuning of the external cavity length. This value is close to the inverse value of the nu(2) line.
