Nd-doped phosphate glass cane laser: from materials fabrication to power scaling tests

Nd-doped phosphate glass cane laser: from materials fabrication to power scaling tests
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 cross-section was selected for the fabrication of a core/cladding cane with a diameter of 800 µm. Laser experiments, performed on a 60 mm-long cane, show laser emission at 1054 nm with output power higher than 2 W and 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 µm region.

Abstract

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 cross-section was selected for the fabrication of a core/cladding cane with a diameter of 800 µm. Laser experiments, performed on a 60 mm-long cane, show laser emission at 1054 nm with output power higher than 2 W and 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 µm region.
