Abstract

The exponential parameters for Stokes and anti-Stokes side band absorption in ZBLAN : Er3+ fiber and bulk samples have been measured to be 9.4 × 10-3 and 14.1 × 10-3 cm, respectively. Different exponential parameters for side bands absorption and non-radiative decay suggest that different phonons are involved. The influence of side band absorption on the Er3+ doped fiber has been estimated.
