Changes in the emission properties of metal targets during pulse-periodic laser irradiation

A scanning electron microscope was used with a pulse-periodic CO₂ laser to discover the laws governing the correlation of the modified microrelief of metal surfaces, subjected to the action of multiple laser pulses, with the emission of charged particles and the luminescence of the irradiated zone. It was established that the influence of sorption and laser-induced desorption on the emission signals may be manifested differently depending on the regime of current generation in the "target–vacuum chamber" circuit.
