Abstract

A 980-nm pump-induced nonlinear refractive-index (n_2) change in erbium-doped (20-m) and ytterbium-doped (20-m) fibers has been measured at 1064 nm by time-delayed photorefractive beam coupling in a copropagating and counterpropagating geometry. It was found that n_2 decreases at the wavelength of the probe beam when the pump beam is present. We present a semiclassical theory based on a four-state system that accounts for the pump-induced change of n_2. Both theoretical and experimental results show that a significant index change, of the order of 10%, can be obtained for cw pump powers as small as10 mW.
