A procedure is presented for determining the parameters of stable resonators characterized by full exploitation of the laser medium. The fundamental mode radiation is generated with an efficiency close to usual multimode one, and in particular it is insensitive to fluctuations of the pump-induced lensing of the laser medium. Experimental verification of the procedure and data about efficiency and beam quality are presented. These resonators, called ‘dynamic stable resonators’, are preferred to unstable resonators in applications needing a highly reproducible uniform intensity distribut
