Abstract

Observation of the time dependence of the up-conversion fluorescence allows the determination of the relative importance of the excited state absorption and energy transfer up-conversion in 0.5% and 50% erbium-doped YAG. Pump radiation up to 10 kW/cm2 shows drastic changes in the effective life time of nearly all excited energy states.
