Abstract

We report what we believe to be the first demonstration of a Kerr-lens mode-locked Cr31:LiSrAlF6 laser that is pumped by a single narrow-stripe AlGaInP laser diode with a diffraction-limited output beam. A novel low-loss three-mirror laser cavity design is described in which strong, localized Kerr lensing was exploited such that 75-fs-duration pulses were obtained for only 36 mW of incident pump power. This pump power was maintained for 18 h by just three AA batteries as the electrical power source. We have shown that mode locking can be sustained for pump powers as low as 22 mW.
