✦ Synopsis

Neodymium octanoate (NdOA) was synthesized from neodymium oxides and dissolved into poly(methy1 methacrylate) (PMMA) forming a solid solution of Nd3+ doped PMMA (Nd-PMMA). Investigation of the absorption spectrum of Nd-PMMA showed that it was similar to that of Nd3+ doped silica glasses, but with about 5 nm of blue shift. The glass transition temperature (T, s) of all the Nd-PMMA samples were about 10°C higher than that of pure PMMA for Nd3+ concentrations of 60-700ppm. The Nd-PMMA was used to draw a fibre. The emission output of the fibre at 585nm was observed under a green source pumping at 532nm by optimization of the Nd3+ concentration and the length of the fibre. Under 1 W pumping radiation, 60pW output was obtained for the fibre with Nd3+ concentration of 70ppm and length of 15 cm.
