Abstract

We simulate supercontinuum generation in a fiber pumped by noise-like laser pulses for possible use in mid-IR spectroscopic breath analysis. The study uses a commercially available InF3 ZBLAN fiber and a Tm-doped all-fiber passively mode-locked laser. The supercontinua are modeled with input laser parameters in two different generation regimes with an average power of 560 mW and pulse durations of 300 and 800 fs. The maximum numerically achieved spectrum extends from 1 to 8.4 μm.
