摘      要：Atoms ionization by the simultaneous absorption of multiple photons has found applications in fiber optics,where it leads to unique nonlinear *** date,studies of the ionization regime have been limited to gas-filled hollow-core ***,we investigate multiphoton ionization of standard optical fibers,where intense laser pulses ionize the atoms constituting the fiber structure itself,instead of that of the filling *** characterize material modifications produced by optical *** formation affects laser beam dynamics over hours long temporal *** damage features are studied by means of optical microscopy and X-ray *** the framework of glass photonics,our results pave the way for a novel glass waveguide micromachining technique.
