摘要

研究了无相位匹配情况下宽带频谱高增益参数下变频的和频产生问题。在强聚焦情况下，二次谐波频谱中出现了一组干涉谱峰，没有相位匹配。理论模型支持的实验数据揭示了相关效应对非相位匹配和频率产生的影响。

Non-phasematched Sum Frequency Generation from Tightly Focused High Gain Parametric Down Conversion

we study the sum frequency generation from high gain parametric down conversion with broadband spectrum in the absence of the phase matching. In the case of strong focusing, a set of interference spectral peaks in the spectrum of the second harmonic appear without the phase matching. Experimental data supported by theoretical modeling reveal the influence of correlation effects on non-phase matched sum frequency generation.
