Influence of the Static Sample Temperature on the Mass Spectra of Alkali Halides and Metals Obtained with Pulsed Laser Induced Ion Generation

Abstract

Abstract Experimental investigations of the interdependence between the ion yield and the static sample temperature at a fixed laser irradiance. between the ion yield and the laser irradiance at different static sample temperatures and between the ion detection threshold irradiance and the static sample temperature are reported. Laser wavelengths of 532 nm. 355 nm and 266 nm have been used to obtain the data. The laser pulse duration was 10 ns. Experimental results for alkali halides and metals are reported and compared. A strong dependence of the experimental parameters mentioned above on the static sample temperature has been observed for alkali halides. In the case of metals only minor effects have been found. In any case the different laser irradiation wavelengths do not significantly effect the experimental results.
