The design and performance of diode-pumped Cr:LiSGAF lasers mode-locke
d by Kerr-lens made-locking and a solid-state saturable absorber are d
escribed, The different regimes of operation of the laser made-locked
by the saturable absorber are discussed. Both lasers generate 100-fs p
ulses with average powers of 40 mW and low fluctuations.
