Optical Pumps for Lasers

performance(engineering), manufacturing, efficiency*lasers, *yttrium aluminum garnet, lithium yttrium tetrafluoride, nd:yag lasers, *neodymium lasers, fluorescent dyes, holmium glass lasers The objective of this program is to increase both the efficiency and the reproducibility of optical pumps for pulsed Nd:YAG lasers. This report covers work carried out from 17 September 1971 to 16 March 1972. Xenon lamps with cerium-doped quartz envelopes were tested and were found to provide less useful light output than xenon lamps with normal quartz envelopes; however, lamps with cerium-doped envelopes may be useful because they can help reduce degradation of organic coolants, laser rods, and cavity reflecting surfaces. Surrounding the lamp with a fluorescent dye solution first increased the useful Nd:YAG fluorescent light output but the dye was quickly bleached and rendered ineffective. Preliminary measurements on lamps for pumping holmium lasers indicated that xenon flash lamps are the most suitable for this purpose.
