WebFigure 2-1: Measured optical constants of fused silica (SiO 2 glass). The influence of the UV-edge on the refractive index is clearly visible. [1] Regions of strong dispersion, with steep slopes in the refractive index curve, correspond to absorption bands, this can be clearly seen in figure 2-1. If for example the UV transmittance WebAt low pulse energies just above the modification threshold (~ 100 nJ for 0.6-NA focusing of 800-nm, 100-fs pulses), a smooth refractive index modification has been observed in fused silica (Itoh et al., 2006), which is attributed to densification from rapid quenching of the melted glass in the focal volume (Chan et al., 2001 ).
