The incorporation of an optical timing fiducial onto a time-resolved x-ray streak record permits one to precisely relate the x-ray emission to the incident laser pulse. At the Laboratory for Laser Energetics, our approach to recording fiducials is twofold. In addition to recording the x-ray emission on a bifurcated photocathode, we also streak the incident laser light at 351 nm, which is scattered from the target and an independent signal at 4..omega../sub 0/ (264 nm), which is derived by frequency quadrupling a tiny fraction of the OMEGA laser driver output. The signal at 4..omega../sub 0/ is transported through the vacuum wall to the streak camera photocathode via fiber optics. A 200-A-circle aluminum layer on mica is utilized for the UV sensitive photocathode. We will present examples and further details of this system.
