1.1-W cw Cr:LiSAF laser pumped by a 1-cm diode array

Opt Lett. 1997 Jan 15;22(2):99-101. doi: 10.1364/ol.22.000099.

Abstract

We demonstrate 1.1-W cw output power from a diode-laser array-pumped Cr:LiSAF laser based on a concept that allows for pumping low-gain solid-state lasers at reduced temperature rise. We discuss scaling to higher powers as a function of diode power and define a figure of merit for evaluating given diode lasers as pump sources for low-gain solid-state lasers.
