Abstract

We demonstrated efficient generation of intense vacuum ultraviolet pulses at 133 nm directly from a 400-nm filament in argon gas. The conversion efficiency was significantly enhanced by adding a coaxial 267-nm pump pulse to dramatically ameliorate the phase matching conditions, as the dispersion originated from neutral atoms was compensated by additional free electrons stemmed from enhanced ionization induced by dual-color fields. Such a robust all-optical phase-matching control was shown to be dependent upon the pump intensity and temporal delay between the dual-color fields.
