Abstract We report for the first time on tunable room temperature cw laser action of a transition metal laser material. In Cr3+:GdScGa-garnet crystals almost the total fluorescence is channelled into the broad band4 T 2→4 A 2 transition. The fluorescence lifetime is τ=120 μs. Laser pumping in the blue-green and yellow-red spectral range yields pump thresholds around 250 mW and slope efficiencies up to 11%. The wavelength of the free running Cr3+ laser is centered at 777 nm.
