Abstract

A 24W liquid-cooled CW 3μm fiber laser with a multimode-core Er-doped ZBLAN fiber has been developed. The output power of 24W and an optical-to-optical efficiency of 14.5% (with respect to incident pump power) were obtained with 975nm diode pumping. Efficient cooling was implemented by a combination of fluid cooling over the entire length of the fiber and conductive cooling at both end faces of the fiber. Consequently, stable high-power operation was demonstrated. To our knowledge, this is the highest output power obtained by a 3μm fiber laser. Furthermore, the high power can be further scaled up, since the output power in the present work is limited only by the available pump power.
