“…The dispersion parameters were obtained from a recent experimental characterization of the 7.5 µm indium fluoride fiber based on the use of an array of fiber Bragg gratings 36 and shown in figure 14b. The nonlinear index is assumed to be n 2 = 4.0 × 10 −16 cm 2 /W, lower than the bulk value of 4.3 × 10 −16 cm 2 /W given by Basaldua et al 37 The standard procedure was used to obtain the Raman transfer function. However, because the absolute value of the Raman gain is unknown, we assumed that the fractional Raman contribution was f R = 0.20 to get a good fit with the experimental results.…”

A tunable ultrashort soliton pulse source reaching up to 4.8 µm is demonstrated based on a 2.8 µm femtosecond fiber lasercoupled to a zirconium fluoride fiber amplifier followed by a small core indium fluoride fiber.This demonstration is extendingby 500 nm the long wavelength limit previously reported with soliton self-frequency shift (SSFS) sources based on fluoridefibers. Our experimental and numerical investigation highlighted the spectral dynamics associated with the generation of highlyredshifted pulses in the MIR using SSFS enhanced by soliton fission. This study is intended at providing a better understandingof the potential and limitations of SSFS based tunable femtosecond fiber sources in the 3-5 µm spectral range.
