Lasers with Nuclear Pumping

Reactor and Laser Coupling

“…Luminescent studies of inorganic liquids doped with europium and neodymium using fission fragments as the pump source and the VIR-2 pulsed reactor as the neutron source were performed in the Former Soviet Union [11]. The mixtures used included POCl 3 (Tb 3+ ).…”

“…The emission from the Y 3 Al 5 O 12 Nd 3+ crystal agreed with the model studies and indicated that the lasing threshold for the crystal was exceeded. Experiments in the Former Soviet Union were performed with a fiber neodymium laser pumped with a xenon flashlamp [11]. In this work the fiber was placed inside the lamp between two plates (10 cm by 6 cm) coated with a thin layer of uranium oxide-protoxide.…”

“…A series of experiments on the Eu 3+ (TTA) 3 2P compound were carried out in the Former Soviet Union using the TIBR reactor using various solvents (Ditolyl methane, α-Methylnapthalene, Benzol, Toluene, Xylene, Acetophenol, Acetone, Cyclohexane, Chloroform and Tetrachloride Carbon) [11]. Fluorescence studies of the 5 D 0 line in Eu 3+ were completed.…”

“…Experiments using a solid-state lamp based on a CsI(Tl) crystal was used to drive a neodymium laser [11]. The CsI(Tl) crystal used the BR-1 pulsed reactor to produce the luminescence.…”

“…A YAP:Tm 3+ crystal (with wavelengths between 1.85 and 2.0 μm) was pumped by laser radiation from an argon nuclear-pumped laser (1.79 μm) and a xenon nuclear-pumped laser (1.73 μm) [11]. The laser crystal was 0.5 cm long with a volume of 4 mm 3 .…”
