Abstract

We present comparative investigations on the formation of in-volume nanogratings in a porous glass with both conventionally and spatiotemporally focused femtosecond laser pulses. Our results show that despite the different spatiotemporal characteristics of the light fields produced at the foci with the two focusing schemes, nanogratings can be formed in both cases, whereas their structural features are different. We discuss the physical mechanism behind the experimental observations.
