Paper Abstract

The luminescence spectra of the ejected particles from laser ablation of the superconductor was measured with the optical spectrum analyzer. In the experiment, the Y-Ba-Cu-O superconductor was adopted as target. When it was bombarded with excimer laser pulse, the target materials evaporated and luminescence plasma plume was formed above the target surface. By identifying the emission spectrum lines, the types and excited states of the ejected particles was determined. Meanwhile, the characteristics of the velocity distribution and luminescence intensity distribution of the ejected particles were studied by time- and space- resolved spectroscopic techniques.
