Abstract

High-power, continuous-wave (CW) supercontinuum spanning from 1200 to 2100 nm has been generated in an all-fiber configuration. The output of a CW 8-W phosphosilicate fiber Raman laser at 1556 nm was efficiently converted to the supercontinuum in the successive high-nonlinear dispersion-shift fiber with the zero-dispersion wavelength of 1539 nm. The fiber-length and input-power dependences were investigated, and both the spectral broadening and continuum power are found to be strongly affected by the 2220-nm absorption band in silica. An average power of 6.8 W and a 20-dB bandwidth of 900 nm were obtained from the optimal 150-m fiber length. Very flat spectral intensity of 10±1 mW/nm from 1640 to 2015 nm is also a noteworthy feature. Raman-assisted four-wave mixing driven by modulation instability is the most possible mechanism of the presented CW supercontinuum generation and well explains the spectral cutoffs.
