Self-focusing and filamentation of ultrashort mid-infrared laser pulses, whose wavelengths fall in the anomalous group velocity dispersion range of dielectric media, produces supercontinuum radiation with unprecedented spectral coverage [1, 2]. Under such conditions, a qualitatively new filamentation regime is accessed, where simultaneous compression in space and time leads to formation of quasi-stationary...
Group velocity dispersion (GVD) plays a significant role in ultra-short pulse propagation in a fiber. Advent of photonic crystal fibers made it possible to tune the fiber dispersion properties and fabricate the fibers with one or two zero dispersion wavelengths (ZDW). This work describes the successful dispersion measurement of fundamental mode in the novel antiresonant hollow core fiber (ARHCF) [1,...
