In this paper, we summarize crystal physical, spectroscopic, and laser characteristics of Ti:sapphire. We report the recent results of our study on the residual infrared absorption of the crystals, tunable lasers, and frequency doubling of the lasers. The recent development of various Ti:sapphire lasers in the world is briefly reviewed.
