Ultrashort electron bunches of few femtoseconds length are highly desirable for a large number of applications, such as ultrafast electron diffraction, free-electron lasers or for external injection into plasma wakefields. A precise knowledge of the longitudinal phase space is crucial for these applications and in order to optimize bunch compression. However, measuring the bunch length or even the current profile becomes increasingly challenging for ever shorter bunches. We will present a new method to diagnose ultrashort bunches using laser-driven plasma wakefields and explore its limitations in terms of resolution in time and energy spread.
