摘要：

New Nd:SrWO4 and SrMoO4 crystals (45 mm and 33 nun of length, respectively) were investigated as Raman frequency converters of 50 picosecond Nd:YAG pulses and compared with already previously measured BaWO4 and KGd(WO4)(2) (KGW) tungstate crystals (33 mm and 40 mm of length, respectively). A forward SRS action was achieved in both new crystals. During the experiment the threshold energy of stimulated Raman process, generated wavelengths, and conversion efficiencies were measured. Single-pass first Stokes conversion efficiencies eta reached 25% and 21% for Nd:SrWO4 and SrMoO4 crystals, respectively. These values were compared with the maximal first Stokes efficiencies measured for BaWO4 (eta = 25%) and KGW (eta = 22%). The threshold energy was comparable for crystals BaWO4, Nd:SrWO4, and SrMoO4. The SRS effect in KGW crystal started for similar to25% higher pump energy. Our study shows that new Nd:SrWO4 and SrMoO4 crystals are other promising materials for picosecond Raman radiation generation.
