摘要:
The optical pumping of Ce**3** plus :YLiF//4 at 308 nm leads to the formation of transient and stable color centers due to an excited-state absorption which photoionizes the cerium ions. Measurements of the temperature dependence of the transient center lifetime and the dependence of the single-pass gain on pump repetition rate are presented.
