Selecting an optimum resonator to achieve diffraction-limited directionality of the emission of high-power electroionization pulsed CO2 lasers
Abstract
The angular divergence of the emission of a high-power electroionization pulsed laser was measured for various parameters of an unstable telescopic resonator in order to investigate the possibility of reaching the diffraction limit. An analysis of experimental results indicates that the diffraction limit can be attained by using an unstable telescopic resonator with an aperture that is somewhat less than the discharge gap, with an extension of 2 or more, and with a far-extended output mirror.
