Description
Laser field diagnostic has long been limited by dimensions of obtained information and one-shot measurement ability. The term “dimension” refers to spatiotemporal distributions, but also physical quantities completely defining a light field including amplitude, phase and polarization. Conventional diagnostic systems realize multi-shot or incomplete measurements of laser optical field, but are limited to characterize actual low-repetition, complex “structured” laser fields. A full characterization of spatiotemporal quantities of light field is essential, as the accelerated electron bunch distributions and qualities are highly dependent on the incident complex laser. A full characterization of complex structured light fields will be a potential tool for the single shot, high dimensional electron bunch diagnostic. Here we proposed the technique of high-dimensional single-shot optical field diagnostic, resolving full-dimensional information of arbitrary spatiotemporal inhomogeneous laser fields. It is believed that this novel light detection technique can not only be further compactly implemented for pre-diagnostic of electron acceleration, but also observe 3D electron bunch dynamics.
