Abstract

Generation of sub-$50\mathrm{fs}$ vacuum UV pulses with more than $2.5\mathrm{\mu J}$ energy at a $1\mathrm{kHz}$ repetition rate is reported. The pulses at $160\mathrm{nm}$ are produced using noncollinear difference-frequency four-wave mixing between the fundamental and third harmonics of an amplified Ti:sapphire laser in argon. While the pulse duration is maintained by increasing the phase-matching pressure, noncollinear interaction improves the conversion efficiency by 1 order of magnitude in comparison with the previous results in collinear geometry.
