Abstract
We demonstrate generation and measurement of intense deep-ultraviolet light pulses with a duration of (FWHM of the intensity envelope) and a wavelength distribution between 230 and . They emerge via direct frequency upconversion of sub- laser pulses of a carrier wavelength of focused into an Ne-filled, quasi-static gas cell. Dispersion-free, third-order autocorrelation measurements provide access to their temporal intensity profile.
