Abstract (en)

[origin: WO9944399A1] A test piece (1) such as a sheet of metal is irradiated by a high power laser (4) in a vacuum chamber (2). The electromagnetic properties of the plasma formed at the irradiated metal surface are measured by three probes (5, 6, 7), these properties being indicative of the chemical nature of the irradiated surface.
