摘要：

We describe the performance of a soft aperture Kerr-lens mode-locked femtosecond Cr:LiSAF laser continuously tunable from 809-910 nm. Pumped by two 500 mW near-diffraction limited red diode lasers, the mode-locked laser generated near-bandwidth limited pulses with durations as short as 70 fs with a repetition rate of 88 MHz. The amplitude modulation required to sustain stable mode-locking was produced by a soft aperture generated within the Cr:LiSAF crystal as a result. of the excellent quality of the focused pump beam. The soft aperture nature of the mode-locking ensured stable day-to-day operation of the laser. (C) 1998 Elsevier Science B.V.
