Evaluation of laser beam interaction with carbon based material - glassy carbon

Abstract

Laser beam interaction with carbon based material (glassy carbon) is analyzed in this paper. Nd3+:YAG laser beam (1.06?m i.e. near infrared, NIR range) in ms regime with various energy densities is used. In all experiments, provided in applied working regimes, the surface damages have occurred. The results of laser damages are analyzed by light and electron scanning (SEM) microscopies. Program Image J is executed for quantitative analysis of generated damages based on micrographs obtained by light and SEM microscopes. Temperature distribution in exposed samples is evaluated by numerical simulations based on program packages COMSOL Multiphysics 3.5 in limited energy range.
