摘要：

We report on the fabrication and characterization of two Nd-doped active glasses and two compatible cladding compositions. The materials were synthesized to be compatible in terms of thermal expansion and characteristic temperatures. The glass system with higher refractive index and absorption crosssection was selected for the fabrication of a core/cladding cane with a diameter of 800 mu m. Laser experiments, performed on a 60 mm-long cane, show laser emission at 1054 nm with output power higher than 2 Wand efficiency above 40%. These values, obtained on a very simple geometry, are promising for the development of short-length cane lasers and amplifiers for emission in the 1 mm region. (C) 2017 Elsevier B.V.
