摘要

为了提高转换效率，提出了一种新的四通正交变频方案。在低输入基波激光强度为76 MW/cm2的情况下，该方案在1064 nm的KTP中实现了倍频的高效率，转换效率超过80%。以607 mJ的1064 nm基频激光为输入，在10 Hz频率下获得486 mJ的二次谐波输出。

Highly efficient second harmonic generation by using four pass quadrature frequency conversion

A novel frequency converter architecture of four-pass quadrature frequency conversion scheme was developed aiming to achieve high conversion efficiency. A high conversion efficiency of more than 80% has been achieved in this scheme for frequency doubling of 1064-nm in KTP with a low input fundamental laser intensity of 76 MW/cm2. A second- harmonic output of 486 mJ was obtained with 607 mJ of the input 1064-nm fundamental laser at 10 Hz.
