Abstract
In order to protect most the final optics hardware of megajoule-class lasers from the radiations produced by ignition shots, it is desirable to steer the laser beams after frequency conversion. Using a transmission grating etched in fused silica is an attractive solution for 3 omega beam steering. The conceptual design of a focusing system based on this device is reviewed. The issues of pulse temporal shear and beam transport are addressed. The compatibility of 3 omega gratings with other beam steering devices is assessed in view of possible evolution of the focusing system during the lifetime of the laser facility.
