By introducing a non-destructive single-shot EO sampling technique, we succeeded in clocking the electron beams generated from LWFA. Statistics on the electron arrival time unambiguously demonstrated that LWFA in the self-injection regime is not necessarily jitter free. In the non-bubble self-injection case, the electron beams could have a timing gap up to 1ps for different plasma density. As a reference, stable arrival times at various plasma densities were demonstrated by using N2 gas in the ionization injection regime. With superior data attainability and non-destructive single-shot characteristics, this method could be a candidate as real time electron timing monitor for LWFA experiments.
