摘要：

Non-linear absorption is observed in Er3+-doped fluoroindate glass (in mol% 37InF(2):20ZnF(2):20SrF(2):16BaF(2): 2GdF(2):2NaF:1GaF(3):2ErF(3)) when the sample is irradiated with a CW laser emitting at 650 nm. An intensity dependence of the optical transmittance is detected. Saturation and sequential absorption of two photons are responsible for the decrease of 50% in the transmittance. The results are explained by simple models which are solved based on rate-equations for the populations of energy levels. (C) 1999 Elsevier Science B.V. All rights reserved.
