Abstract

Many types of lasers, particularly semiconductor and gas lasers, tend to oscillate naturally in several transverse Fox-Li modes simultaneously.1 Although single fundamental-mode operation has been one of the goals in recent laser structure developments, the presence of multiple modes may in certain applications (eg. lithography, micrometrology, speckle noise suppression) be desireable due to the associated spatial coherence reduction.
