Beschreibung
Laser wakefield acceleration (LWFA) is a candidate to build next generation of electron accelerators due to its huge acceleration field in a plasma medium. Progresses of intense laser technologies contributed to developments of multi-GeV [1,2] and high repetition-rate electron beams [3] by LWFA. Recently, we accomplished upgrading one of our PW beamlines to 4 PW peak power [4] and started applying it to LWFA experiments. In addition to multi-PW lasers, we installed a 5-Hz 100-TW laser and a 1-kHz sub-TW laser to examine novel LWFA schemes and develop high-repetition-rate electron beams. In this presentation, we will briefly summarize the current status of LWFA research at Center for Relativistic Laser Science (CoReLS); LWFA with multi-PW laser pulse, nanoparticle-assisted LWFA, and control of LWFA by elliptically shaped laser focus.
