Abstract. Multirod dynamically stable linear resonators with equal beam spot sizes within each rod, despite of the individual thermal optical power of the rods, are introduced. It is shown that reduced optical power of the thermal lenses allows for reliable high-power operation. Ways to control power density loading of the intracavity optical elements as well as resonator misalignment sensitivity are discussed.
