Abstract
Since cavity-phase matching has been experimentally realized, the efficiency is limited to 20%. In this Letter, we successfully achieved a conversion efficiency as high as 41% with a slope efficiency of 48.5% using cavity-phase matching, by reflecting the pump beam at the end surface of the crystal. The high performance of the device makes it a promising candidate to substitute for quasi-phase-matching material.
