✦ Synopsis

Neodymium octanoate was synthesized from neodymium oxides and dissolved in poly(methy1 methacrylate) (PMMA), forming a solid solution. The investigation of the absorption spectrum of Nd3+-doped PMMA showed that the spectrum was similar to that of Nd3+-doped silica glasses. The Nd3+-doped PMMA was used to draw a fiber and an unclad Nd3+-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 Nd3+ concentration and the length of the fiber. Under 1 W pumping radiation, a 60 fiW output was obtained for the fiber with a Nd3+ concentration of 70 ppm and the length of 15 cm. 0 1996

## Abstract ## Background and Objective Photo‐thermal converters have been successfully used in laser surgery; however, most of the currently used converters are likely to be damaged in the operations due to various problems, preventing them from being efficiently and repeatedly used in laser ther
