CONTINUOUSLY PULSED LASER DEVICE FOR SURVEILLANCE.
Abstract
As pointed out in the second quarterly report, work on this contract has been reduced to caretaker status pending improvement in Nd:YAG crystals. In the meantime, Hughes Aircraft Company, under Company sponsorship, has been investigating the tradeoffs between tungsten lamps and xenon flashlamps as pumps for pulsed Nd:YAG lasers. The results obtained so far are given in some detail in this report and indicate that below 6 kc repetition rate, flashlamps are superior to tungsten lamps while above 6 kc repetition rate the reverse is true. The actual cross-over region is not sharply defined so that from 3 kc to 8 kc repetition rate other system considerations could force the choice of one or the other types of lamps. (Author)
