International audience; Multilayer dielectric gratings (MLDG) are key optical components of Petawatt-class laser that are used to compress short pulses of high intensities. Laser-induced damage can occur on the top area of the components, typically a

Chirped pulse amplification has been widely implemented in high power laser chains. It consists of a set of diffraction gratings used to stretch and compress short laser pulses. In the case of high power laser chains, the compression stage is followe

Downstream impact induced by defects of sol-gel antireflection layers is studied in the high power lasers context. First results of propagation and laser damage tests are presented about defects dimensionally similar but morphologically different.
