Multiwavelength, picosecond, synchronously-pumped Pb(MoO₄)₀₂(WO₄)₀₈ Raman laser oscillating at twelve wavelengths in a range of 1128-1360 nm

In this Letter, a mixed Pb(MoO4)0.2(WO4)0.8 as a new, to the best of our knowledge, active medium with optimized content for a synchronously pumped multiwavelength Raman laser with a combined frequency shift is presented. The unique structure of this crystal resulted in oscillations at 12 closely spaced output wavelengths in a spectral range from 1128 to 1360 nm. The strongest pulse shortening in comparison with nominally pure scheelite-like crystals has been achieved.
