Abstract

A comparison is made between the beam quality parameter M2and a new times-diffraction-limit-factor (TDL) for two high peak power XeCl lasers. The laser systems, equipped with unstable resonators, emit beams with different geometrical characteristic and optical quality. The results show that the M2-factor is always larger than the TDL value and this discrepancy increases if the beam is almost diffraction- limited. A novel method to obtain the far-field profile of coherent superGaussian-like beams and a simple technique to estimate the beam angular stability of a pulsed laser are also presented. ©2005 Copyright SPIE - The International Society for Optical Engineering.
