Abstract

New Nd:SrWO₄ and SrMoO₄ crystals (45 mm and 33 mm of legnth, 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 reached 25% and 21% for Nd:SrWO₄ and SrMoO₄ crystals, respectively. These values were compared with the maximal first Stokes efficiencies of previously studied crystals measured in the same experimental setup yielding: BaWO₄ (η = 25% and KGW (η = 22%). As concerned the threshold - it was comparable for BaWO₄, Nd:SrWO₄, and SrMoO₄. The SRS effect in KGW crystal started for ~25% higher pump energy. Our study shows that new Nd:SrWO₄ and SrMoO₄ crystals are other promising materials for picosecond Raman generation.
