Four methods of beam expanding in nitrogen laser pumped dye lasers were investigated, and compared. The most important parameters of beam expanders were considered i.e. the magnification, and the efficiency of feedback. Besides the optimalization of multiple-prism beam expanders, a new combined beam expander was studied, and optimalized. This combined, prism-grating beam expander produced high efficiency of feedback in a wide range of magnifications and easily produced single mode operation with 4% energy conversion efficiency.
