Abstract : Emission from metal-halide vapors under pulsed-discharge excitation has been studied in a search for new laser systems. Only minor cavity-feedback effects have been observed in the case of cuprous bromide, while these effects were more pronounced for mercuric bromide. Attempts to produce single-pass super-radiant emission from laser-pumped vapors of organic molecules were unsuccessful. A new diagnostic technique to monitor gain-loss effects in pulsed discharges is described. Afterglow character and high-gain are reported for the O(III) laser transitions. Two new laser lines of O(III) have been observed in the uv. (Author)
