The generation of high pulse and average power radiation in eye-safe spectral region by the third stokes generation in barium nitrate Raman laser

The generation of high pulse and average power radiation in the eye-safe region (wavelength around 1.599 μm) by the third Stokes generation in a barium nitrate Raman laser was demonstrated by pumping with 10 ns pulses of a Nd:YAG laser. Converted pulse energy was up to 93 mJ (peak power was 10 MW) at a pump energy of 300 mJ, which corresponds to a quantum efficiency of 47%. The average output power of the third Stokes radiation was 1.8 W.
