Abstract

Monomode guiding over 100 Rayleigh lengths (10 cm) of high intensity ultrashort laser pulses (1016W/cm2120 fs) has been demonstrated in hollow dielectric capillary tubes (45-70 μm internal diameter) without inner wall damage. Analytical predictions for coupling conditions and damping length are confirmed experimentally for tubes under vacuum. With 5 to 40 mbar of He gas in the tube, when laser ionization occurs the energy and duration of the transmitted pulse decrease while its spectrum is broadened.
