Anomalous fluorescent decay of LiF:UO(3) under high-intensity excitation.
Single crystal samples of LiF:UO(3) were tested for laser action. While no unambiguous evidence for laser oscillations was observed, the material did show anomalous fluorescent decay under the highintensity pumping in basically two respects: (1) a short-lived (20-microsec to 30-microsec) micro-spike was exhibited, followed by (2) a period of unusually slow decay. To explain the observations, a depopulation mechanism is proposed and discussed.
