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 458nm lines as a pump source, 58fs pulses centered at 845nm were generated. The average output power is 30mW, and time-band product is 0.331, assuming a sech2 pulse shape. Neither acousto-modulator nor physical aperture or slit were used in this cavity.
