Abstract: A novel transparent 4.76 at.% Tm:(Lu2/3Sc1/3)(2)O-3 "mixed" sequioxide ceramic is synthesized by hot isostatic pressing (HIP) at 1800 degrees C / 195 MPa in an Ar atmosphere. Its structure is studied by scanning electron microscopy, X-ray diffraction, and Raman spectroscopy. The spectroscopic properties of the Tm3+ ion are described within the Judd-Ofelt theory, which resulted in intensity parameters of Omega(2) = 2.429, Omega(4) = 1.078 and Omega(6) = 0.653 [10(-20) cm(2)]. For the F-3(4) -> H-3(6) transition, the maximum stimulated-emission cross-section sSE is 7.15 x 10(-21) cm(2) at 1951 nm. The radiative lifetime of the 3F4 state is 4.01 ms. Under diode-pumping at 802 nm, a microchip Tm:(Lu, Sc)O-2(3) ceramic laser generated similar to 1 W at 2100 nm with a slope efficiency of 24%. The spectroscopic and laser properties of the Tm:(Lu, Sc)O-2(3) ceramic are compared with those of a Tm: LuScO3 single crystal. The ceramic exhibits very broad and flat gain cross sections, which is promising for ultrashort pulse generation.
