Investigation of the misalignment of a resonator with a telescopic angular selector in a photodissociation laser

An experimental investigation was made of the characteristic features of the emission of a photodissociation laser with a resonator containing a telescopic angular selector. A method for aligning this resonator was developed and a study was made of the influence of misalignment of each of the resonator elements. The energy losses were found to correspond to the losses in the equivalent plane-parallel resonator. The advantages of the resonator employed was the maintenance of the angular width and direction of the maximum in the spatial distribution when a wedge deformation appeared in the resonator. The axial brightness was considerably higher than in the equivalent misaligned plane-parallel resonator without a selector.
