Abstract

We report time-averaged and time-resolved emission spectra subsequent to laser-induced optical breakdown of aluminum in laboratory air and in hydrogen gas. The microplasma generated by nominal 10   ns IR laser radiation shows Stark-broadened and shifted atomic lines. An analysis of the H α and H β Balmer series lines and selected aluminum lines allows one to determine electron number density in the range of 0.01 10 × 10 18 cm 3 early in the plasma decay. Atomic and molecular features are investigated for diagnostic applications in laser material processing.
