Abstract

Structural, optical and spectroscopic properties of Tm3+:Lu2O3 ceramics were studied. CW laser operation at 2068 nm with an output power of up to 34 W and a slope efficiency of 44% was obtained. Q-switched ocsilation with a pulse duration of 100-150 ns and a repetition rate of 1-10 kHz was achieved. Passive mode locking was achieved using an ion-implanted InGaAsSb quantum-well based SESAM or single graphene layer. Transform-limited pulses as short as 180 fs are generated at 2076 nm with an average output power of 400 mW and a pulse repetition frequency of 121.2 MHz. (© 2013 WILEY-VCH Verlag GmbH & Co.
