Absolute excited-state absorption cross section and fluorescence quantum efficiency of Cr(3+):gadolinium scandium gallium garnet.
Excited-state properties of the laser material Cr(3+):Gd(3)Sc(2)(GaO(4))(3) were determined by a photocaloric technique. The excited-state absorption cross section at 650 nm is (3.6 +/- 0.6) 10(-20) cm(2), and the fluorescence quantum efficiency at ambient temperature is (91 +/- 1)%.
