Understanding the Femtosecond Laser-Solid Interaction Near and Beyond the Material Damage Threshold

Abstract

Under the recently completed BRI program, the PI has established a new femtosecond solid dynamics laboratory (FSD) dedicated to the study of the fundamentals of femtosecond laser damage as a function of various parameters, laser wavelength, pulse width, pulse number, experimental ambience (air/vacuum/other), polarization and angle of incidence, target solid material conductivity(metal/semiconductor/insulator), band gap, and surface morphology (nano/micro-structured surface), and the PI's team has worked synergistically in designing and performing experiments, analyzing results, and developing a unified femtosecond laser damage simulation framework, which allowed direct benchmarking of simulation results with experimental observation without any free parameters.
