Abstract

We have achieved efficient room-temperature flash-lamp-pumped laser operation in titanium-doped sapphire. The laser has a threshold of 20 J, a slope efficiency of 0.5%, an output energy in excess of 300 mJ, and a tuning range (with our present optics) of 720–920 nm. Ways of reducing the lasing threshold and increasing slope efficiency are discussed.
