Chromium doped GdScGa-Carnet (Cr:GSGG) exhibits broadband fluorescence in the 700-900 nm region. Growth of this material and lasing at 790 nm with 1 2 laser pumping was initially reported by Struve et al.1 Zharikov et al.2 subsequently reported flashlamp pumped lasing of a 3.9 mm by 40 mm Cr:GSGG rod. In this paper we report on lasing performance of a flashlamp pumped Cr:GSGG laser rod and its lasing threshold for different operating temperatures. Evidence is presented that points to excited state absorption as a limiting factor in this material's performance.
