Laser-induced damage in multilayer dielectric gratings due to ultrashort laser pulses
Solid State Lasers for Application to Inertial Confinement Fusion (ICF)
Chirped pulse amplification is increasingly used to produce intense ultrashort laser pulses. When highefficiency gratings are the dispersive element, as in the LLNL Petawatt laser, their susceptibility to laser induced damage constitutes a limitation on the peak intensities that can be reached. To obtain robust gratings, it is necessary to understand the causes of short-pulse damage, and to recognize the range of design options for high efficiency gratings. Metal gratings owe their highdoi:10.1117/12.228281 fatcat:xk3qj47xgzep3it276je237liy
