Abstract

We demonstrate that in a short Ar cell, generation of the fifth harmonic from 12 fs pulses at 810 nm directly results in ultrashort vacuum UV pulses at 162 nm . They have a spectral width of 5 nm and a duration of 11 ± 1 fs (1.4 times the transform limit), as measured by cross correlation with the fundamental pulses. Their energy (estimated to 4 nJ ) turned out to be sufficient for use as a pump in time-resolved experiments.
