Both the rate and probability of the growth of laser-induced damage sites in fused silica depend on several parameters. In this two-part paper, we investigate the impact of the laser parameters on damage growth. In Part 1, we present statistical meas

Damage probability versus damage density: analysis from tests using small beams versus large beams

Autor: Roger Courchinoux, Charles Bouyer, Jean-Yves Natoli, Romain Parreault, Matthieu Veinhard, Florian Tournemenne, C. Rouyer, Stéphane Bouillet, Laurent Lamaignère

Publikováno v: Laser-induced Damage in Optical Materials 2020.

The paper aims to compare the results obtained with the same laser source with a large beam and with small beams. These latest were shaped from phase objects implemented to obtain several small beams from a single larger beam. The consistency of the
