We demonstrate an efficient approach for enhancing the spectral broadening of long laser pulses and for efficient frequency redshifting by exploiting the intrinsic temporal properties of molecular alignment inside a gas-filled hollow-core fiber (HCF)

A conventional hollow core fiber (HCF) scheme is implemented to investigate spectral broadening of Titanium:Sapphire (Ti-Sa) femtosecond laser pulses in saturated hydrocarbon molecules compared to unsaturated ones. While the saturated molecules exhib

Here, we report the first time observation of the formation of highly-stable multidimensional solitary states (MDSS) in gas-filled Hollow-core fibers. The MDSS have broadband red-shifted spectra with an uncommon negative quadratic spectral phase at o

Pulse compression based on non-linear propagation in a gas-filled hollow core fiber (HCF) is amongst the common techniques to generate few-cycle laser pulses [1]. Although very efficient, the major disadvantage of this method is the need to use expen

Compression of low energy ultrashort laser pulses using a hollow core fiber (HCF) filled with 1-1 difluoroethane (C2H4F2), also known as R152a, is demonstrated. A 45 fs, 16 µJ Ti:Sapphire laser pulse is spectrally broadened in an HCF filled with R15
