A Sm+2/Sm+3 codoped aluminosilicate glass optical fiber was fabricated by use of modified chemical-vapor deposition in conjunction with an aerosol-delivery technique. A permanent index change of 7.6 × 10-5 was induced in the fiber by irradiation of 1 W of multiline output from an Ar-ion laser. Bleaching of a broad absorption band of Sm+2 in the visible range was also observed, and it is believed that photoionization of Sm+2 → Sm+3 + e plays an important role in the induced photorefractivity.
