Abstract

We report, for the first time to the best of our knowledge, a watt level cw fiber laser at 2 μm from a piece of 40-cm-long newly developed highly thulium-doped ( 3.76 × 10 20 ions / cm 3 ) tungsten tellurite glass double cladding fiber pumped by a commercial 800 nm laser diode. The maximum output power of the fiber laser reaches 1.12 W . The slope efficiency and the optical–optical efficiency with respect to the absorbed pump are 20% and 16%, respectively. The lasing threshold is 1.46 W , and the lasing wavelength is centered at 1937 nm .
