Abstract

Investigations of parameters of the ablation specie produced by laser ablation from the CdTe targets were carried out. Optical emission spectroscopy and quadrupole mass spectroscopy methods were used for measurement of ablation species properties. Quantitative and qualitative parameters of ablation species were studied by optical emission spectroscopy. The dependences of the velocities of ablation components and they kinetic energies on the ablation parameters were established, as well. It was found that the ablation of CdTe targets by laser pulses with threshold power possessed a congruent character. In this case, analysis of mass-spectra of ablation species generated by high-power laser pulse shown that it was consisted only Cd and Te atoms, but with various degrees of ionization state. We established that parameters of ablation species have a strong the dependence on laser pulses regimes and parameters of background ambience.
