摘要
本文中将倍频晶体分割成无数多个小倍频单元,并导出每个倍频单元中的谐波功率与倍频效率。然后利用积分求和得出了整个晶体中总的高斯光束倍频效率。最后以KDP晶体为例讨论了计算结果。
In this paper, we divided the double frequency crystal into numerous small double frequency units and derived the harmonic power and the double frequency efficiency in each unit. Then we get the total double frequency efficiency in the whole crystal by using integral method. Finally we discussed the calculation result about KDP crystal.
