Abstract

The design of ellipsoidal plasma mirrors (EPM) for the PEARL laser facility is presented. The EPM achieved a magnification of 0.32 in the focal spot size and the corresponding increase in focused intensity is expected to be ∼ 8. Designing 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 1023 W/cm2 . A retro-imaging based target alignment system is also described, which is used to align solid targets at the output of the ellispoidal mirrors (numerical aperture of 0.75 in this case).
