title: Influence of self-focusing of ultrashort laser pulses on optical third-harmonic generation at interfaces.
abstract: We report on the third-harmonic generation of femtosecond laser pulses at interfaces. We measured slabs of different types of optical glasses and demonstrated that the asymmetric intensity profile observed for a tightly focused beam can be explained by self-focusing effects.
