Neodymium octanoate was synthesized from neodymium oxides and dissolved in poly(methylmethacrylate) (PMMA), forming a solid solution. The investigation of the absorption spectrum of Nd 3+ ‐doped PMMA showed that the spectrum was similar to that of Nd 3+ ‐doped silica glasses. The Nd 3+ ‐doped PMMA was used to draw a fiber and an unclad Nd 3+ ‐doped PMMA optical fiber was made. The emission output of the fiber at about 585 nm was observed under green source pumping at 532 nm by optimization of the Nd 3+ concentration and the length of the fiber. Under 1 W pumping radiation, a 60 µW output was obtained for the fiber with a Nd 3+ concentration of 70 ppm and the length of 15 cm. © 1996 John Wiley & Sons, Inc.
