Abstract
A phase-locked staggered ridge array waveguide gas laser includes a body that circumferentially bounds an internal space extending along a central plane and containing a gaseous lasing medium. The gaseous medium is excited at radio frequency with attendant light emission from the gaseous medium. Mirrors are so positioned relative to the body as to provide lasing of the light emission. Two arrays of ridges extending into the internal space along a height dimension partition the internal space into two pluralities of laser resonator cavities each sustaining a guided mode of the lasing light emission. Each of the cavities extends longitudinally of the body and is spaced from an adjacent cavity in a width direction of the internal space. The ridges of each array are offset relative to those of the other array by substantially a half of the spacing between the ridges of each array and are so configured that a cavity of one of the pluralities alignedly opens into a portion of each of two adjacent ones of the cavities of the other plurality. Auxiliary ridge portions that are truncated to delimit respective gaps at the central plane may be provided midway between and coextensively with the ridges of each array.
