Abstract

An unstable resonator for a laser based on two Nd:YAG active elements with induced thermal lenses is proposed and investigated. The output beam divergence greater by factor 2 than the diffraction limit is achieved. The radiation power of the laser with the resonator proposed has been obtained 20% below but with the 30 times greater on-axis intensity as compared to the ordinarily used resonator in a commercial laser of a similar type.
