A Tm:LuYO3 crystal was grown by the optical floating zone method for the first time. The XRD pattern shows that it belongs to the cubic crystal system (Ia(-)3 space group). The absorption spectrum was used to investigate the emission properties with the help of the Judd-Ofelt theory. The emission cross-section at 2056 nm is 1.95 x 10(-20) cm(2). The Tm:LuYO3 crystal exhibits broad absorption band at around 800 nm with the FWHM of 48 nm and wide emission band at around 2 mu m with the FWHM of more than 200 nm. The potential utility of the Tm:LuYO3 crystal as tunable laser medium at similar to 2 mu m can be expected.
