We have demonstrated stable and self-sustaining Kerr-lens mode locking
of a Cr:LiSGAF laser pumped by AlGaInP laser diodes. A hard aperture
near one end of the laser provides the necessary amplitude modulation.
This all-solid-state system generates transform-limited 100-fs pulses
, tunable from 810 to 860 nn. The average power at 830 nm is 35 mW, wi
th fluctuations of much less than 1%. The thermal properties of Cr:LiS
GAF will permit scaling of these results to higher power.
