Abstract

A permanent index change of 0.0051% was induced in Sm⁺²/Sm⁺³ doped aluminosilicate fiber by irradiating 2W 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. The origin of the photosensitivity in the Sm doped optical fiber is the bleaching of Sm⁺² ion absorption bands enhanced by multiphoton processes.
