The overall objective is to produce more efficient pulsed optical pumps for erbium lasers. Both xenon and alkali-metal vapor lamps are being studied. Laser materials both glass and YAG were selected and their absorption and excitation spectra determined. Fluorescence life times, sensitizer transfer characteristics and decay processes have been catalogued. Thirty-six xenon lamps of various bore diameters and pressures and two cesium lamps were constructed. Initial light output measurements on xenon lamps indicate that the useful light output is independent of the pulse length and current density for pulse lengths of 0.5 to 2.5 milliseconds rendering optimization of this lamp type difficult. Design criteria for alkali metal power supplies were established and cesium lamps were operated. Author
