Study of a collinear single-shot-type cross-correlator for laser timing applications

摘要

We propose and study the use of a single-shot, collinear, tilted-front cross-correlator scheme for relative pulse timing measurements. In a very simple geometry, sub-0.5-fs resolution and larger than 3-ps instantaneous time window in relative pulse timing measurement are demonstrated. In addition, the scheme is shown to be practically immune to the changes of the energy of the monitored pulses exceeding 10 %. On the basis of the obtained results, the scheme can be expected to find applications in diagnostics and stabilization of timing jitter and drifts of pulses originating from different sources.
