The design of ellipsoidal plasma mirrors(EPMs)for the PEARL laser facility is *** EPMs achieve a magnification of 0.32 in focal spot size,and the corresponding increase in focused intensity is expected to be about *** and implementing such focusing optics for short-pulse(<100 fs)systems paves the way for their use in future high-power facilities,where they can be used to achieve intensities beyond 1023W/cm^(2).A retro-imaging-based target alignment system is also described,which is used to align solid targets at the output of the ellispoidal mirrors(with a numerical aperture of 0.75 in this case).
