| Abstract: | Spectral broadening of radiation emitted by a femtosecond Cr:forsterite laser in highly nonlinear fibers (HNLFs) has been investigated. Tapered HNLFs as well as fibers with constant dispersion and dispersion varying over the fiber length are investigated. The nonreciprocal effect of spectral broadening in fibers with varying dispersion is observed. A supercontinuum is obtained in the range from 990 to 2100 nm. |
