Abstract

A spectrometer system for studying excited state absorption of ions in crystals is described. Pulsed xenon short arc lamps and keyed photomultipliers are used to measure the transmission after optically pumping the ions into an excited state. A wide dynamic range of absorption coefficients of excited states with lifetimes down to less than 100 μsec can be measured. A repeatability near the shot noise limit is obtained.
