Abstract

A permanent index change of 5.1×10−5 was induced in a Sm+2/Sm+3 co-doped aluminosilicate fiber by irradiating 1W of multi-line output from an Ar ion laser. The photosensitivity was detected by measuring a shift in LP11 mode cutoff wavelength. Bleaching of a broad absorption band in the visible was also observed. Photo-ionization of Sm+2 is likely to be dominant mechanism.
