Paper Abstract

We study the formation of laser-induced Hertzian fractures on silica output surfaces at high incident influences initiated by surface bound metal particles. Hertzian fracture initiation probability as a function of incidence influence is obtained for two particle materials. The resulting modified damage density curve shows prototypical features determined by the surface-bound particles population. The data is further used to calculate the coupling coefficient between incident energy and the ejected plasma momentum.
