Abstract
We demonstrate a diode-pumped Cr: LiSAF laser with a pure (not quasi) cw output power of 1.1 W. This is to our knowledge the highest reported average output power from a Cr:LiSAF laser. We show that optimized mode-matching of the pump and lasing mode and efficient cooling can lead to output powers in the 1 W range, despite Cr:LiSAF's thermal properties and the nondiffraction-limited pump beams of high-power diode lasers.
