Abstract: We present recent results on laser system that is going to be used as a photocathode laser at the REGAE UEDfacility [1] at DESY. One challenge for UED is the so-called space charge, which occurs due to the mutualrepulsion of the electrons and which limits the coherence length and the achievable spatial resolution required forbiological samples. Our approach to overcome this issue is to distribute the 100 fC charge required to generatesufficient diffraction signal to a burst of about 4500 electron bunches, each containing only about 140 electrons.
