Paper Abstract

Based on the results obtained from two high peak power excimer lasers developed in the ENEA Research Centre of Frascati, equipped with different hard-edge unstable resonators, a comparison is made between the widely used M2 beam quality parameter and a newly defined 'times- diffraction-limit' (TDL) factor, pointing out the different meaning of the two coefficients, the respective limitations, and their range of applicability. A simple setup for the beam pointing stability estimation is also proposed.
