Effect of hot electron blast force on ultrafast laser ablation of nickel thin film: erratum

Abstract

The ablation depths of a 200 nm thick nickel film by ultrafast lasers were simulated and improperly compared with the existing numerical results for a bulk nickel target in our paper [Appl. Opt.54, 1737 (2015)10.1364/AO.54.001737APOPAI1559-128X]. The ultrafast laser ablation of a 1 μm thick nickel film is, therefore, simulated here, which demonstrates that the conclusions in our published paper are not affected and that the adopted 1 μm film is sufficiently thick to be used for the simulation of the ablation behavior of a bulk nickel target subject to 1 ps laser irradiation.
