摘要

In this paper we discuss the ultrashort pulse high gradient inverse free electron laser accelerator experiment carried out at the Lawrence Livermore National Laboratory which demonstrated gradients exceeding $200ext{ }ext{ }mathrm{MV}/mathrm{m}$ using a 4 TW 100 fs long 800 nm $mathrm{Ti}:mathrm{Sa}$ laser pulse. Due to the short laser and electron pulse lengths, synchronization was determined to be one of the main challenges in this experiment. This made necessary the implementation of a single-shot, nondestructive, electro-optic sampling based diagnostics to enable time-stamping of each laser accelerator shot with $100ext{ }ext{ }mathrm{fs}$ accuracy. The results of this experiment are expected to pave the way towards the development of future GeV-class IFEL accelerators.
