Abstract: We have examined the feasibility of undistorted subpicosecond pulse transmission at peak powers of up to 100 MW and a wavelength of 1030 nm in a hollow-core revolver fibre having a core filled with atmospheric air or argon. A hollow-core revolver fibre has been fabricated which has a low-dispersion (β2 ≈ –0.25 ps2 km-1) transmission band in the spectral range of ytterbium and neodymium lasers. Conditions for the nonlinear (soliton) regime of megawatt picosecond pulse propagation over up to 1-km lengths of revolver fibre in atmospheric air and argon at pressures in the range 10-5 to 1 atm have been found theoretically. We have experimentally demonstrated transmission of pulses of 0.8-ps duration and up to ~100-MW power over an ~3-m length of revolver fibre with the minimum possible distortion of their shape and spectrum.

Keywords: subpicosecond pulses, solitons, hollow-core fibre, revolver fibre, Kerr nonlinearity, stimulated Raman scattering.
