Abstract
A femtosecond Kerr-lens mode-locked Cr:LiSGaF laser based on a compact cavity geometry is demonstrated. With a combination of 488, 476, and 458 nm lines as a Dump source, 58 fs pulses centered at 845 nm were ge nerated. The average output power is 30 mW, and time-band product is 0 .331, assuming a sech(2) pulse shape. Neither acousto-modulator nor ph ysical aperture or slit were used in this cavity.
