Similarity in ruthenium damage induced by photons with different energies: From visible light to hard X-rays
Original language description
We performed combined experimental and computational research on damage processes in ruthenium thin films induced by femtosecond lasers with various photon energies. We present an experiment with an optical laser at normal incidence conditions and compare it with previously reported experiments at grazing incidence conditions with XUV and hard X-ray photons, covering a large range of photon energies. Analysis of ablation craters in Ru shows very similar crater morphology and depth of about 10–20 nm for all considered irradiation conditions. Simulations of light-matter interactions are performed with our combined Monte Carlo and two-temperature hydrodynamics approach. The simulation results show that the primal cause of eventual ablation is Auger decay of core-shell holes. Our results suggest that such mechanism is universal in a wide range of photo nenergies at grazing incidence conditions, when the photon absorption depth is smaller than the photoelectrons range.
