High-gain Raman induced multiple Stokes and anti-Stokes generation in monoclinic multiferroic MnWO4 single crystals

Multiple Stokes and anti-Stokes generation in the monoclinic tungstate MnWO4 was observed under one-micron picosecond excitation. All the recorded Raman induced laser lines were identified and attributed to the SRS-promoted vibration mode (at approximate to 879 cm(-1)) of the crystal.
