Paper Abstract

The solution method of a diffraction problem for a multilayer diffraction structure enabling us to analyze the diffraction coupler (DC) with an efficiency of 80% in the first order is discussed. The DC of 62% efficiency in the first order has been manufactured by the photolithography method in conjunction with ion-beam surface treatment. A resonator with DC as an output mirror has been investigated experimentally. The beam output has been performed through the zero order of DC. The stepped change in generation in the range from 9.18 to 10.82 mm has been obtained. A condition for concurrent generation on several neighboring lines has been investigated.
