Paper Abstract

A converging cavity is introduced in the frequency-doubling experiment to increase the efficiency. In this experiment, an annular collimated laser beam produced by Nd:YAG laser with confocal resonator is introduced into the converging cavity as fundamental light. A BBO is positioned in the converging cavity. As propagating in the converging cavity, the fundamental beam profile becomes smaller and smaller. In the theory, the conversion efficiency could be approach 100%. Our experimental result shows that the conversion efficiency is improved significantly compared with the single pass configuration.
