Abstract
Laser-induced damage threshold of gratings remains the
main limiting factor towards generating higher-energy compressed pulses
(terawatt and petawatt). HORIBA Jobin Yvon has first developed the
manufacturing of large gold coated gratings, dimensions up to half a meter.
Then we have developed large multilayer dielectric (MLD) gratings for
working at 1.053 microns with 2 to 3 times higher damage threshold than gold
coated gratings for ps pulses, and higher efficiency (up to 96% averaged
over the full aperture). In addition these large MLD gratings are optimised
for mosaic (tiling) configurations, in which the total useful grating length
may reach 1 meter or more.
