单谐振光学参量振荡器中色散诱导高阶横模的产生

Dispersion-induced generation of higher order transversal modes in singly-resonant optical parametric oscillators

Kai Druhl

摘要:

我们研究了高阶横模在单谐振OPO模型中的影响,使用数值解和模式扩展,包括多达两个径向模式。数值解和双模解在负色散下比单模解预测更低的阈值和更高的转换。零阶径向模中的相对功率范围从正色散和小负色散的约88%到较大负色散的48%,其中大部分较高模含量在第一模中,并且在较高模中小于2%。

英文摘要:

We study the effects of higher order transversal modes in a model of a singly-resonant OPO, using both numerical solutions and mode expansions including up to two radial modes. The numerical and two-mode solutions predict lower threshold and higher conversion than the single-mode solution at negative dispersion. Relative power in the zero order radial mode ranges from about 88% at positive and small negative dispersion to 48% at larger negative dispersion, with most of the higher mode content in the first mode, and less than 2% in higher modes.
