| Abstract: | In this paper, by compute analysis and theory testimony the ways are proposed to restrain divergence or diffraction of tiny light beam with light power distributions outputing from source, with the propagation media. The experiment of principle proved that ways are applicable. A practical need for use can be satisfied fully. |
