Abstract

Our laser-matter interaction program requires the conversion of our OCTAL laser from 1.06 μm to 0.355 μm. Fused silica is used to realized the focusing lens and the last optics (KDP windows, debris-shield, etc). A damage test facility at 3ωo was build in CEA Limeil in order to compare the performance of the different French manufacturers production (polished fused silica was provided by SORO, REOSC, BERTIN ESO, STIGMA-OPTIQUE, ELECTRO-QUARTZ).
