Time shaping of ultra-short UV pulses has been performed using a specially designed acousto-optic programmable dispersive filter in KDP material. A time shaping window up to 5 ps has been obtained in the 260–410 nm range. A temporal/spectral characterization of shaped pulses on this broad UV spectral range is presented. The efficiency at shorter wavelength is limited by two-photon absorption. However several µJ is obtained at the output of the device allowing chemistry coherent control experiment.
