摘要

In this work, we set out to develop a laser-induced breakdown spectroscopy (LIBS) method for monitoring the homogeneity of optical glasses in terms of chemical composition. A quantitative LIBS-based method for studying lead distribution over the surface area of lead silicate glasses is proposed. The parameters of laser radiation acting on the surface of lead silicate glasses (pulse energy, laser pulse repetition rate, laser wavelength, delay between the pulse and the analytical signal registration) are optimized. The minimum step of scanning the chemical composition over the surface area of a sample was established to be 300 μm.
