Abstract
The change of the matrix structure of glass is investigated during and after irradiation with ultrashort pulsed laser radiation (100 fs < tp; < 3 ps) at the wavelength λ = 810 nm. The dynamics of the plasma expansion and the stress formations are visualized by time-resolved Normarski-photography. Optical microscopy visualizes the structural changes in glass. The spatial stress distribution and the refractive index change are shown in the time range 100 fs < t < 120 ns. The ionization state of atoms and/or the formation of color centers has been investigated by transient absorption spectroscopy (TAS) in the time regime 100 fs < t < 120 ns. The temporal change of the spectra shows different regimes, which can be explained by the electron and phonon relaxation.
