We have developed a laser-plasma vacuum ultraviolet light source (LPLS) for the purpose of using it as an excitation light source in experimental studies of Desorption Induced by Electronic Transitions (DIET). In comparison with the synchrotron light source, LPLS has an advantage of being intense in short duration. The pulse width of the order of 10 ns makes it possible to obtain higher time resolution in a time-of-flight measurement of desorbed particles.
