Abstract
Recently, extensive studies have been focused on the laser parameter dependence of the breakdown threshold in order to obtain an in-depth understanding of the mechanism for laser-induced optical breakdown (LIOB). However, much less attention has been paid to altering the breakdown threshold and achieving a controllable breakdown by modifying the material, although LIOB in well-designed materials has a wide range of potential applications. In (his study, we demonstrate that one can notably alter the LIOB threshold of a material by incorporating metal nanoparticles, which significantly enhance the electric field localized at their immediate surroundings.1
