英文摘要	Spectra and laser operation at 2 mu m of Tm:GdScO3 crystal are investigated for the first time. The low symmetry in GdScO3 crystal broadens emission spectrum (269 nm) of Tm3+:F-3(4) -> H-3(6) transition, which is the widest in Tm3+ doped crystals. The emission cross-sections at 1975 nm are approximately 0.23 (E//X), 0.23 (E//Y) and 0.28 (E// Z) x 10(-20) cm(2), respectively. The fluorescence lifetime of Tm3+:F-3(4) is 3.68 ms. Pumped by a 793 nm laser diode, the output power yields 4.53 W with the slope efficiency of 25%. All results indicate Tm:GdScO3 a promising candidate for 2 mu m tunable and ultrashort lasers.
