A high-power and widely tunable Ti: sapphire laser dual-end pumped by a 10 kHz 532 nm pulsed laser with an output wavelength of 720–890 nm was demonstrated. An effective thermal management was achieved by a dual-end pumping scheme and an elaborate symmetrical flat cavity design, which greatly improved the upper limit of pump power. When the pump power was 41.5 W, a maximum output power of 10.36 W at 800 nm was obtained with a linewidth of 2 nm and a pulse duration of 17 ns. The corresponding conversion efficiency was 25 %.
