Recent research progress of laser plasma interactions in Shenguang laser facilities

摘要

cqvip:Wereport experimental research on laser plasma interaction(LPI)conducted in Shenguang laser facilities during the past ten years.The research generally consists of three phases:(1)developing platforms for LPI research in mm-scale plasma with limited drive energy,where both gasbag and gas-filled hohlraum targets are tested;(2)studying the effects of beam-smoothing techniques,such as continuous phase plate and polarization smoothing,on the suppression of LPI;and(3)exploring the factors affecting LPI in integrated implosion experiments,which include the laser intensity,gas-fill pressure,size of the laser-entrance hole,and interplay between different beam cones.Results obtained in each phase will be presented and discussed in detail.
