Abstract

Nd:YAG laser with the wavelength of 213 nm was used for the study of laser beam interaction with compact samples of different characteristics and composition. Particle size distribution for different conditions of laser ablation (laser spot, pulse energy, repetition rate) was measured using optical aerosol spectrometer Welas 2000 (Palas, Germany) providing the measurement of particle number distribution in the size range 300 - 17000 nm. Alternatively, in combination with CNC unit the spectrometer measures the total particle number concentration in the size range from 10 to 17000 nm. Signals of isotopes were monitored using quadrupole ICP-MS Agilent 7500ce. The structure and composition of particles was studied after their collection on polycarbonate membrane filter (200 nm, Cyclopore, Whatman) using electron microscopy and electron microprobe (EMP). Tungsten carbide and steel samples provided comparable number concentrations and sizes of particles using the same laser ablation conditions. The contribution of bigger particles was up to 0.1% of all measured particles . In the case of glass samples the occurence of bigger particles was minimal. Time dependences showing the change of particle concentrations during 400 s laser ablation for different ablation conditions were measured.
