We performed 2D Particle-In-Cell plasma simulations to study the interaction of an ultra-thin film plasma
mirror (PM) with a high-intensity laser for two cases; 1) interaction with a main-pulse and 2) interaction
with a back-reflected pulse from the interaction target. PM’s reflectivity decreased from 79% to
0.1% after expansion of the plasma mirror when the back-reflected pulse reentered the mirror. The result
indicates that a harmful back-reflected light from the main target can be removed by using an ultra-thin
film PM.
