Abstract [en]

In this paper, we report an all-fiber supercontinuum source pumped with ultra-short pulses at 1.9–2.0 μm, covering over an octave (1200–2400 nm). We investigated the shot-to-shot stability of the supercontinuum generated in a commercially available highly nonlinear fiber (HNLF) of different lengths, ranging from 5 to 80 cm, by employing the dispersive Fourier transform method. Our study shows that using shorter HNLFs significantly improves the shot-to-shot stability while maintaining the broad spectral coverage. The supercontinuum generated in HNLFs shorter than 10 cm is characterized by excellent stability despite the anomalous-dispersion characteristic of the fiber. The presented source is characterized by exceptional simplicity, showing readiness for outside-of-lab applications.
