Mid-infrared supercontinuum generation from 1.6 to >11 μm using concatenated step-index fluoride and chalcogenide fibers
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 sulf...

Zusammenfassung: | 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 ∼4.5 μm, ∼6.5 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. |
