A1 WINDSOR, MAURICE W., TRW SPACE TECHNOLOGY LABS REDONDO BEACH CALIF., PB Defense Technical Information Center PP Ft. Belvoir YR 1962 AB Results highly suggestive of laser action have been obtained for benzophenone and a chelate of terbium in rigid organic glasses at 77 K.A resonant laser cavity employing multiple-layer, dielectric-coated, confocal mirrors was constructed. This was used for the low-temperature glass studies. Extension of observations to liquid systems is a simple matter using the above cavity. A high power flash apparatus of 12,800 joule capacity was constructed for excitation purposes. A technique was developed for flashing lamps immersed in liquid nitrogen. Techniques were developed for incorporating aromatic compounds and chelates into plastic rods for laser evaluation. Lifetimes of aromatic compounds in plastics were measured. Rareearth ions and chelates were evaluated for potential laser action in liquid solutions and experimental studies were started. Novel ways of experimentally increasing quantum yields are under consideration. (Author).
