Pump-probe studies of absorption saturation and optical gain in Ce:LiCaAlF6 ultraviolet active medium

Abstract

Aim of this work was to investigate nonlinear absorption of pump radiation in UV spectral range of Ce3+:LiCaAlF6 crystalline active medium. We were able to evaluate excited state absorption cross-section at pump wavelength (266 nm) and recombination probabilities by means of computer simulation. © Published under licence by IOP Publishing Ltd.
