Abstract
Monomode guiding over 100 Rayleigh lengths (10 cm) of high intensity ultras hort laser pulses (10(16) W/cm(2), 120 fs) has been demonstrated in hollow dielectric capillary tubes (45-70 mu m internal diameter) without inner wal l 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. [S0031-900 7(99)09293-5].
