Abstract

Generation of sub-20-fs UV pulses with more than $300\mathrm{\mu J}$ energy at $268\mathrm{nm}$ is reported. First, the UV pulses are produced by successive second-harmonic and third-harmonic (TH) generation of $805\mathrm{nm}$ pulses of a $1\mathrm{kHz}$ Ti:sapphire laser amplifier. The spectral broadening of TH pulses is realized in a filament, generated in argon. The produced pulses are compressed in a simple double-pass prism-pair compressor. Starting from $100\mathrm{fs}$ pulses, we achieve a fivefold pulse shortening.
