| Abstract: | In the P8per the concept of average radii of pumped beam in a solid medium being a criteria of efficiency is presented. Dependences of slope and threshold on volume and ellipticity of pumped light are analysed. Based on the theory of mode-coupling,requirements of a coupling system for design and adjustment are deduced, Finally a coupling system consiting of a couple of expanding prisms is investigated in detail. |
