Experimental demonstration of a synthetic aperture compression scheme for multi-Petawatt high-energy lasers

Opt Express. 2010 May 10;18(10):10088-97. doi: 10.1364/OE.18.010088.

Abstract

We present the experimental demonstration of a subaperture compression scheme achieved in the PETAL (PETawatt Aquitaine Laser) facility. We evidence that by dividing the beam into small subapertures fitting the available grating size, the sub-beam can be individually compressed below 1 ps, synchronized below 50 fs and then coherently added thanks to a segmented mirror.
