Abstract

Plasma plume expansion and crater formation in the interaction of Nd-YAG laser beam (TEM_oo-mode, 532 nm, 6 ns pulse duration and 10 micrometers waist at FWHM) with various metal targets in air were investigated. The craters formed at the surfaces were measured with 0.1 micrometers longitudinal and 0.5 micrometers transversal resolutions. Laser plasma expansion during laser pulse/surface interaction was measured by ICCD camera with 3 micrometers spatial and 1 ns temporal resolutions. These measurements were performed with different optical filters in the following spectral ranges (250< (lambda) <400 nm, 300<(lambda) <600 nm, 600< (lambda) <800 nm).
