Diode-pumped Tm:Lu 2 O 3 thin disk laser

We report the first diode-pumped Tm:Lu2O3 laser operation in thin disk design. Average output powers of 1.4 W and slope efficiencies of 32 % with respect to incident pump power were achieved in quasi-CW pumping. © 2011 Optical Society of America OCIS codes: (140.3480) Lasers, Diode Pumped; (140.3410) Laser Resonators
