Abstract

Supercontinuum (SC) sources have extensive applications in tomography, spectroscopy, and communications. Numerous applications, including ultrahigh-resolution optical coherence tomography, free-space broad-spectrum optical communication, high-speed imaging, spectroelectrochemical ellipsometry, and spectral sensitivity evaluation are based on SC. SC generation in optical fibers could be easily observed in the anomalous dispersion region near 1.5 μm. Indeed, in the normal dispersion region, the modulation instability induced by cross phase modulation could also generate the SC. In this study, an all-fiber-integrated high-power tandem-pumped random Raman laser amplifier is built for SC generation in normal dispersion region. The output power exceeds 1 kW. And the spectrum covers the range from 1.07 μm to 1.6 μm.
