We describe a diode-pumped Kerr-lens mode-locked Cr3+:LiSrAlF6 laser t
hat produces 50 mW of 70-fs pulses in the 820-890-nm range when pumped
by two red diodes of 400 mW each. By using a lower-transmission outpu
t coupler me have demonstrated for the first time to our knowledge a s
elf-starting regime with an output power of 10 mW and 55-fs pulses. (C
