由于腔相位匹配已经在实验上实现，所以效率被限制在20%。在这封信中，我们成功地实现了转换效率高达41%，斜率效率为48.5%，使用腔相位匹配，通过反射泵浦光在端面的KTiOPO（4）晶体。该器件的高性能使其成为替代准相位匹配材料的一种有希望的候选材料。
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 KTiOPO(4) crystal. The high performance of the device makes it a promising candidate to substitute for quasi-phase-matching material.
