Abstract

In this communication, the authors report on the first high power emission obtained using a solid non-filamented core fully-aperiodic large pitch fiber manufactured by the REPUSIL method which is based on the sintering and vitrification of micrometric doped silica powders. Using a simple laser cavity, an average output power of 252 W was achieved for the first time in such a fiber with an available pump power of 400 W, corresponding to an optical-to-optical efficiency of 63 %. The M² measurements have shown an excellent beam quality with values close to 1.4 at full power and lower than 1.3 for signal power lower than 215 W.
