A low-threshold self-starting Kerr-lens mode-locked Ti:sapphire laser is demonstrated that uses a tight-focusing cavity design in conjunction with a semiconductor saturable- absorber mirror (SESAM). With 3 % and 12 % output couplers, we achieve mode-locking thresholds as low as 390 and 600   mW , respectively. Stable femtosecond laser pulses with average power of 114   mW are generated at a pump power of 1.2   W , which corresponds to a typical duration of 17   fs and bandwidth of 47   nm . Mode-locking operation is achieved in a pump power range of 600   mW to 4.8   W at an output coupling of 12 % ; the advantages of using a SESAM for low-power mode-locking operation are demonstrated.
