Abstract

A high-power diode-cladding-pumped Ho3+-doped fluoride glass fiber laser operating in cascade mode is demonstrated. The 5I 65I7 and 5I 75I8 laser transitions produced 0:77W at a measured slope efficiency of 12.4% and 0:24Wat a measured slope efficiency of 5.2%, respectively. Using a long fiber length, which forced a large threshold for the 5I75I8 transition, a wavelength of 3:002 μm was measured at maximum output power, making this system the first watt-level fiber laser operating in the mid-IR.
