Direct shaping of picosecond high energy deep ultraviolet pulses

Abstract

We demonstrate temporally shaped pulses in the deep ultraviolet spectral range (270 nm) with energies up to 37 μJ using an efficient prism stretcher and an acousto-optic programmable dispersive filter (AOPDF) applied directly in the UV. The scheme allows for arbitrary phase and amplitude shaping of picosecond UV pulses at high energy in a simple and efficient way.
