Characterization of White Light Supercontinuum
In this chapter, the measurements of the white-light continuum characteristics in the spectral, spatial and temporal domain are presented and discussed. Of major scientific interest, is for once, the behavior of the white-light continuum to the applied input power of the pump-laser beam. The goal is to later obtain an efficient and possibly flat spectrum (here, moderate slope in narrow spectral intervals), with a large spectral broadening and sufficient white-light fluence F WL , for the formation of LIPSS on the samples. The investigation also includes the determination of the output power of the filtered spectra after the three short pass filters.
