N2 - In this study, detailed characteristics of the optical near-field based ablation-induced plasma are investigated. A Cr thin metal film samples are ablated using visible and near infrared nanosecond laser pulses coupled through an optical near-field fiber probe. The ablated plasma evolution is visualized through time-resolved emission imaging and further analyzed via spectral measurement. Unveiled qualitative differences in optical near-field ablation configuration are discussed in comparison with optical far-field ablation. The measured results support implementation of laser-induced breakdown spectroscopy based on optical near-field ablation.
