Abstract
We report on passively Q-switched operation of a diode-pumped Er-Yb:glass l aser with a Co2+:MgAl2O4 plate as a saturable absorber. Optical pulses with peak power exceeding 2 kW and a pulse length of 2.3 ns have been generated . Single-longitudinal-mode Q-switched operation at 1.53 mum has been obtain ed by use of the Co2+:MgAl2O4 plate as an intracavity etalon. A discussion of the optimal Er3+ concentration as well as optimization of the cavity des ign is included. (C) 2000 Optical Society of America OCIS codes: 140.3500, 140.3540, 160.5690, 160.6990.
