Abstract
A high power phase coupled waveguide laser comprising a plurality of symmetrically disposed lasing members disposed around the outer periphery of an annular enclosure. The laser includes an annular body of dielectric material having a multiplicity of laser cavities formed therein in a symmetrical annular array. The body includes a central bore having conduits extending therethrough for providing a flow of cooling fluid. The heat path between the cavities and the cooling fluid is symmetrical for all cavities. This provides equal conditions for all laser cavities in the array and ensures phase coupling of all cavities.
