Influence of Bending on Ultrafast Nonlinear Dynamics in Gas-filled Hollow-core Fiber

A multiple octave-spanning supercontinuum generation spanning 400-5000 nm is generated in a Xe-filled hollow-core anti-resonant fiber pumped at 3 μm with pulses of 100 fs duration and 15 μJ energy. A significant reduction of the spectral broadening under tight bending conditions has been demonstrated.
