Abstract
New amplitude modulators using LiNbO3 (LNO) bulk crystals have been developed at CEA/LV in order to create short temporal pulse shaping with a monomode power laser pulse before amplifying and focusing on a target. A 4 ns profile can be controlled by a growing high voltage pulse applied on electrodes pasted to the crystal. After having computed the voltage capacities and the efficiency of the Pockels effect in terms of contrast, shape quality, pulse duration and rise time, we experimented shots on Phebus facility to validate the performances of the device. This baseline of pulse shaping can be adopted in case of smoothing a broadband laser beam with an optical fiber in the LMJ facility design.
