Steady state operating characteristics of femtosecond Ti:sapphire lasers

The steady-state characteristics of the femtosecond Ti:sapphire lasers are discussed with the help of the mode-locked equation derived by us. The characteristics are both valuable in the research of the mode- locking mechanism and guidable to optimized design of the cavity configuration. The optimum parameters of the cavity configuration are reported. With the optimum arrangement, the self-mode-locked Ti:sapphire lasers produces pulses as short as 60 fs, and for the pump power of 4 W, the average output power can exceed 300 mW. The pump power threshold for CW laser oscillation is 1 W, and for self-mode-locked oscillation is about 3 W.
