The dependences of all-solid-state tunable Ti:sapphire laser output poweron the resonator intracavity losses and output coupler transmission were analyzed theoretically and tested in experiment.According to the experimentally tested intracavity losses and transmission,the design of the laser was optimized and higher and more stable output powers were obtained.With the pump power of 8 W,the output power of 2 W at the wavelength of 792 nm with slope efficiency of 37.6% was obtained.The intensity fluctuation of the output laser was less than ±0.5% during 1 h,and the tunable range was from 720 to 820 nm.When the laser was locked,the frequency stability was better than ±134 kHz over 10 s and ±3.3 MHz in 15 min in the totally tunable range from 720 to 820 nm.
