研究了铀（III）在CaF/sub 2/晶体中的受激红外发射，该晶体两端为0.05摩尔%的铀和银薄膜。用液氦冷却晶体，用脉冲氙放电激发晶体，在2.5 μ处隔离辐射并检测。示波器的探测器响应迹线显示受激辐射与背景光的比值为bbb1000，并且存在弛豫振荡，峰值的数量随着氙放电功率的增加而增加。(D.L.C.)
Stimulated infrared emission from uranium(III) in CaF/sub 2/ was studied using a single CaF/sub 2/ crystal with 0.05 mole% uranium and silver films on both ends. The crystal was cooled with liquid helium and excited by a pulsed xenon discharge, and the radiation was isolated at 2.5 mu and detected. Oscilloscope traces of the detector response showed the ratio between the stimulated emission and the background light to be>1000 and relaxation oscillations to be present, the number of spikes increasing with the power of the xenon discharge.
