| Abstract: | The spectra and dynamics of the line emission of a lead erosion laser plasma at a distance of 1 mm from the target are investigated. The plasma is ignited in a vacuum (P=3–12 Pa) with a pulse-periodic neody-mium laser (τ=20 ns, f=12 Hz, W=(1–2)×109 W/cm2, and λ=1.06 µm). The data obtained are used to analyze the emission dynamics and the mechanism of formation of the laser plume. |
