ABSTRACT
We demonstrate an all-fiber supercontinuum source that generates a continuous spectrum from 1.6 µm to >11 µm with 417 mW on-time average power at 33% duty cycle. By utilizing a master oscillator power amplifier pump with three amplification stages and concatenating solid core ZBLAN, arsenic sulfide, and arsenic selenide fibers, we shift 1550 nm light to â¼4.5 µm, â¼6.5 µm, and >11 µm, respectively. With 69 mW past 7.5 µm, this source provides both high power and broad spectral expansion, while outputting a single fundamental mode.
