单共振连续波参量振荡器中的衍射效应

Diffractive effects in singly-resonant continuous-wave parametric oscillators

Kai Druhl

摘要:

本文详细地数值研究了泵浦光和信号光共线聚焦对低损耗单谐振参量振荡器转换效率的影响。结果给出的最大泵浦损耗和泵浦功率水平所需的各种数量的耗尽,作为泵和信号共焦参数的函数,为kI/kP=0.33和0.50。结果发现,泵浦功率阈值功率比的函数的泵浦损耗最大损耗的比例同意与平面波预测在5%以内,为广泛的聚焦条件。所观察到的趋势被解释为导致强度和相位依赖机制。

英文摘要:

This paper presents a detailed numerical study of the effect of focusing on the conversion efficiency of low-loss singly-resonant parametric oscillators with collinear focusing of pump and signal. Results are given for the maximal pump depletion and for pump power levels required for various amounts of depletion, as functions of pump and signal confocal parameters, for kI/kP=0.33 and 0.50. It is found that the ratio of pump depletion to maximal depletion as a function of the ratio of pump power to threshold power agrees with the plane-wave prediction to within 5%, for a wide range of focusing conditions. The observed trends are explained as resulting from intensity and phase dependent mechanisms.
