摘要：

The fluorescence spectra ranging from 400 to 1000 nm were investigated on highly Er3+-doped fiber pumped by a 1.48-mum laser diode. A strong green emission was observed. An investigation of the fluorescence intensity dependence on pump power revealed that the green emission is attributed to successive excited-state absorption through a three-step process and also that saturation of the atomic levels that contribute to the emission occurs.
