100kW peak power picosecond thulium-doped fiber amplifier system seeded by a gain-switched diode laser at 2µm
We report on the generation of picosecond pulses at 2µm directly from a gain-switched discrete-mode diode laser and their amplification in a multistage thulium-doped fiber amplifier chain. The system is capable of operating at repetition rates in the range of 2MHz - 1.5GHz without change of configuration, delivering high-quality 33ps pulses with up to 3.5µJ energy and 100kW peak power, as well as up to 18W of average power. These results represent a major technological advance and a 1 order of magnitude increase in peak power and pulse energy compared to existing picosecond sources at 2µm.

Abstract

We report on the generation of picosecond pulses at 2µm directly from a gain-switched discrete-mode diode laser and their amplification in a multistage thulium-doped fiber amplifier chain. The system is capable of operating at repetition rates in the range of 2MHz - 1.5GHz without change of configuration, delivering high-quality 33ps pulses with up to 3.5µJ energy and 100kW peak power, as well as up to 18W of average power. These results represent a major technological advance and a 1 order of magnitude increase in peak power and pulse energy compared to existing picosecond sources at 2µm.
