We systematically investigate positive and negative slope resonators with joint stability zones and show the advantages and drawbacks of the different designs. As a result we achieve more than 60% fundamental mode extraction efficiency in Nd : YAG with regard to multimode output, without using any compensation for thermally induced bifocusing or birefringence. For fully polarized output, we obtain more than 53% extraction efficiency in fundamental mode. To our knowledge, these efficiencies are the highest so far reported for single-rod and double-rod diode pumped solid-state laser. (AU)
