摘要

研究了由外部激光泵浦的谐振腔内二次谐波的产生问题。在SHG中发生的基本过程是吸收频率为ω的2个光子和发射频率为2ω的1个光子。Drummond等人[1]已经证明,这个问题可以用电场(复)振幅的两个常微分方程来建模:其中上横表示复共轭。

From harmonic to pulsating periodic solutions in intracavity second harmonic generation
We consider the problem of Second Harmonic Generation (SHG) inside a resonant cavity, pumped by an external laser. The elementary process that takes place in SHG is the absorption of 2 photons of frequency ω and the emission of one photon at frequency 2ω. Drummond et al[1] have shown that this problem can be modeled by two ordinary differential equations for the (complex) amplitudes of the electrical fields: where overbar means complex conjugate.
