The characteristics of two prism ring lasers for cw operation have been experimentally studied. With improved compensation for aberrations due to astigmatism and coma, cw ring lasers operated in the traveling‐wave mode provide high output efficiency, stable narrow bandwidth in multimode and single‐mode operation, and a broad tuning range.
