Based on the rate equations describing the operation of the Er3+, Pr3+-codoped ZBLAN fiber lasers with different pump configurations, theoretical calculations that relate to the population characteristics and optimization of CW operation of high power Er3+, Pr3+:ZBLAN double-clad fiber lasers are presented. Using the measured ET (energy-transfer), ETU (energy-transfer-upconversion) and CR (cross-relaxation)...
Narrow line-width fiber grating 1535 nm erbium laser was demonstrated by introducing fiber grating F-P cavity. It was composed by high Er3+ doped fiber, 980/1550 nm WDM and fiber grating F-P cavity. Linear and ring cavity experiments were demonstrated respectively. In the experiment, pumped by 976 nm diode laser, the associated fiber lasers with frequency selecting by fiber grating F-P cavity exhibited...
