Efficient high energy 1st, 2nd or 3rd Stokes Raman generation in IR region

The efficient high energy generation of the 1st (1.197 μm), 2nd (1.369 μm) or 3rd Stokes (1.599 μm) components in barium nitrate Raman lasers pumped with a 1.064 μm radiation was demonstrated. The energies of more than 100 mJ were obtained in each Stokes component at pump energy of about 300 mJ. The quantum conversion efficiencies were 66%, 44% and 63% for the 1st, 2nd and 3rd Stokes generation, respectively.
