TL;DR: A novel random laser based on a single fiber Bragg grating is demonstrated by pumping the fiber with 976 and 1480 nm pump lasers and the number of emitted modes is observed to be a function of the length of the grating and of the pump power.

Inband-pumped, broadband bleaching of absorption and refractive index changes in erbium-doped fiber
TL;DR: In this paper, the spectra of absorption bleaching of erbium-doped fiber is measured and the refractive index changes inferred through the Kramers-Kronig relations in this true two-level system in order to understand its operation in the external cavity of a laser.
