Abstract

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