The darkening of Tb3+-doped phosphosilicate optical fibers by resonant excitation at 488 nm is found to be almost completely reversible by exposure to off-resonance excitation at 514 nm. The darkening and bleaching are three- and two-photon processes, respectively, and the steady-state absorption of the fiber is controllable by the competition between the two processes.
