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