Description
Experiments using two multi-petawatt laser pulses promise access to experiments with extraordinary field strengths. To perform such challenging experiments, very high stability of the laser parameters must be achieved.
In this study, the main laser pulse parameters are considered (spectral distribution, spatial shape, energy stability and temporal duration) for the purpose of overlapping multiple beams. Data from the HPLS laser diagnostics are collected and analyzed from both a normal day of operations and a day of dual-beam jitter experimental campaign. HPLS stability is measured for each parameter. Complementary, AVESTA system is being upgraded with a second arm, a multi-pass amplifier and a compressor, for future dual beam parameters stability, pulse overlapping and synchronization investigations.
