In this paper, simulated and experimental supercontinuum (SC) generation in the chalcogenide commercial fiber IRF-S-5 are presented. A spectral broadening in the 1.9-3 μm wavelength range is obtained with an average power up to 180 mW by pumping the fiber set-up with a femtosecond Cr:ZnS laser operating at the wavelength λ=2.36 μm. The reported results are obtained by varying the input pulse energy E0 from 0.24 nJ to 1.23 nJ with a repetition rate RR=144.55 MHz and a pulse duration T0=100 fs. Experimental results are compared with the results of simulation obtained via a numerical model that takes into account the fiber geometrical parameters, the dispersion behavior, the nonlinear parameters and the input pulse characteristics. A good correspondence is found.

Abstract
In this paper, simulated and experimental supercontinuum (SC) generation in the chalcogenide commercial fiber IRF-S-5 are presented. A spectral broadening in the 1.9-3 μm wavelength range is obtained with an average power up to 180 mW by pumping the fiber set-up with a femtosecond Cr:ZnS laser operating at the wavelength λ=2.36 μm. The reported results are obtained by varying the input pulse energy E0 from 0.24 nJ to 1.23 nJ with a repetition rate RR=144.55 MHz and a pulse duration T0=100 fs. Experimental results are compared with the results of simulation obtained via a numerical model that takes into account the fiber geometrical parameters, the dispersion behavior, the nonlinear parameters and the input pulse characteristics. A good correspondence is found.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
