SPECTROSCOPIC STUDY OF ATOMIC BEAMS GENERATED BY LASER ABLATION OF MULTI-COMPONENT TARGETS
An experiment is described where Li and Al beams were generated by ablation of thin, multilayer targets using a Q-switched ruby laser with a total energy density up to 30 Jcm**-2. Measurements using laser induced fluorescence and mass spectroscopy were combined to analyze the energy and density distribution and the temporal structure of the beams. The maximum translational energy observed was several eV for Li and an order of magnitude greater for Al with a peak particle density in the range of 10**10 cm**-3 for both Li and Al. The targets were analyzed by optical microscopy and secondary ion mass spectroscopy, providing information about the size of the spots and the structure of the metal before and after the ablation experiment.
