Lasing at 2.72 µm in an Er3+-doped high-purity tungsten–tellurite glass fiber laser

This Letter reports the experimental realization, for the first time to our knowledge, of lasing in an erbium-doped tellurite fiber at 2.72 µm. The key to the successful implementation was the use of advanced technology for obtaining ultra-dry preforms of tellurite glasses, as well as the creation o...
