Energetic Blue-shifted DW Emission in Multi-mode Gas-filled Hollow-core Fibers

The dispersive wave emission can be enhanced and blue-shifted by selectively exciting high-order-modes (HOMs) in gas-filled hollow-core anti-resonant fiber pumping at 1030 nm with pulses of 30 fs duration and

energy. Multi-octave supercontinuum spanning 200–1400 nm has been demonstrated by exciting LP02 mode. © 2021 The Author(s)
