Abstract
In Laser-Induced Plasma Spectroscopy (LTPS) measurements a plasma is produc ed by focusing of a laser pulse on a solid sample surface. In this paper th e effect of imperfect focusing on the reproducibility of LIPS measurements is studied in detail, under typical working conditions. Using fast optical and spectroscopic diagnostics, it is shown that plasma and shock wave dynam ics play a fundamental role on the resulting. LIPS signal when accurate qua ntitative results are needed.
