LASER DEVICES EXPLORATORY INVESTIGATION.

Abstract

Considerable progress has been made in the understanding and attainment of single transverse mode operation in a solid state laser. Application of a mode selection technique to a ruby laser has resulted in single transverse mode operation at twice threshold pumping with a 15 fold increase in brightness. Chromium doped spinel has been grown by flame fusion and flux techniques. Optical and microwave spectroscopy of these crystals in dicates that they are inferior to the spinels occurring naturally. Preliminary experiments on nonlinear optics have demonstrated the generation of Stokes and anti-Stokes frequency shifted lines in calcite and benzene. Measurement of absolute Raman scattering cross sections have been made and the results are found to be consistent with threshold measurements for stimulated Raman scattering (SRS). (Author)
