Abstract
50 mJ Q-switched output at 30 ns pulse duration was demonstrated with a tra nsversely diode-pumped bulk Er3+:Yb3+:glass 1.54 mum laser system of uncomp licated and compact design, using a piezoelectrically driven FTIR shutter. In long-pulse operation, 360 mJ output was obtained for 2.65 J incident opt ical pump energy. Maximum optical slope efficiencies of 20.5% and 5.4% were measured in long-pulse and Q-switched operation, respectively. Optimum Q-s witch timing was studied taking into account the Yb3+ --> Er3+ energy trans fer process and was correlated with free-running delay parameters. (C) 2001 Elsevier Science B.V.
