Paper Abstract

Pulsed laser radiation in the visible spectral range is used to investigate and to modify the surface of wide bandgap materials, in particular fluoride crystals. The processes studied are mainly based on multiphoton interaction and comprise optical second harmonic generation, surface ionization, desorption of positive ions, and the generation of a microplasma. All effects are facilitated by surface defect states, and the materials can be grouped into two classes of different response, according to their defect density.
