Abstract
This work investigates the interaction of 10-ps and 0.6-ps, 1053-nm laser pulses with ≈40 um-diam microparticles located on the surface of a multilayer dielectric mirror. Resulting morphology was examined as a function of fluence and number of pulses (1–10) for four different particle materials (one metal, one glass, and two polymers). Processes of particle ejection, particle-assisted laser-induced–damage, and damage growth are discussed, all of which occur at fluences less than half of the pristine (not contaminated) laser-induced–damage threshold of the mirror.
