Abstract

We demonstrate a high-average-power continuous wave (cw) and cw mode-locked Cr 3 + : LiCAF laser pumped by broad-area laser diodes. In cw lasing experiments, up to 580 mW of output was obtained with 4.35 W of incident pump. A semiconductor saturable absorber mirror was used to initiate stable, self-starting, mode locking. In the cw mode-locked regime, the Cr 3 + : LiCAF laser produced nearly transform-limited, 67 fs long pulses near 800 nm with an average output power of 300 mW . The pulse repetition rate was 120 MHz , with a pulse energy of 2.5 nJ .
