Abstract
A Q-switched pulsed laser resonant cavity having an output coupling mirror with a radially variable reflectivity function across its surface and a magnification level that combine to provide a very high discrimination against transverse modes of oscillation higher than a desired fundamental mode. This resonant cavity is especially adapted for use with injection seeding to limit the longitudinal modes of oscillation to one mode. The cavity arrangement develops a high powered light pulsed beam at its output that also has a uniform intensity profile.
