Abstract

We report the design and performance of a tandem 2µm polarization-maintaining (PM) holmium-doped amplifiers (HDF) pumped with an hybrid pumping at 1150nm and 1860nm. The tandem amplifier consists of a pre-amplifier co-pumped at 1150nm that produces large gain and a 3dB noise figure, while the power booster counter- pumped at1860nm delivers more than 2W output power at 2050nm. This hybrid amplifier configuration can operate efficiently over the whole HDF bandwidth from 2000nm to 2100nm.
