Second-Stokes Raman lasers with large wavelength shift from 1064 to 1316 nm wavelength in PbWO/sub 4/ crystals

High-order Stokes and anti-Stokes stimulated scattering due to the known optical vibration mode and in addition at 320 cm/sup -1/ have been observed. The construction of a new highly efficient second-Stokes Raman laser indicates that it is a general method to extend the number of possible Raman laser wavelengths with large wavelength separation from the fundamental pump.
