摘要：

Ultraviolet loss measurements on germanosilicate fibre samples showing an intense absorption, centred at 242nm, with an associated fluorescence at 413nm are presented. The first direct observation is reported of the bleaching of this 240nm band under the action of ultraviolet irradiation, evidence which is consistent with the Kramers-Kronig model for the photosensitive refractive index change in these glasses.
