Production engineering measure for optical pumps for lasers

This program is directed toward establishing a capability for manufacturing flashlamps that are to be used as optical pumps for Nd:YAG laser systems. This report describes the work carried out during the fifth quarter of the program. The four synthetic fused quartz ETS lamps were life tested in the external trigger mode. The lamps exceeded the minimum laser efficiency requirement at the one million shot point when tested in the simmer mode, but the efficiency was marginal when operated in the external trigger mode. All ETS lamps tested passed the vibration and shock tests. All ETS lamps tested passed the laser output variation test at the one million shot point when operated in both the simmer mode and the external trigger mode. All ETS lamps passed the anti-coincidence pulse requirement at the one million shot point.
