摘要:

目前,二次非线性过程被用于频率梳转移,并从可见光和近红外区域扩展到无法实现直接梳产生的其他光谱范围。然而,频率梳产生已被直接观察到连续泵浦的二次非线性晶体放置在一个光学腔。在同一时间,已提供了一个介绍性的理论描述的现象,表现出显着的类比与三阶克尔微谐振器的动力学。在这里,我们给出了一个概述,我们最近的工作$χ^{(2)}$频率梳产生。此外,我们推广了初步的三波光谱模型的多模梳,并提出了不同的腔场制度的稳定性分析。虽然在一个非常早期的阶段,我们的工作奠定了基础,一类新的高效和多功能的频率梳状合成器的基础上二阶非线性材料。

英文摘要:

Quadratic nonlinear processes are currently exploited for frequency comb transfer and extension from the visible and near infrared regions to other spectral ranges where direct comb generation cannot be accomplished. However, frequency comb generation has been directly observed in continuously-pumped quadratic nonlinear crystals placed inside an optical cavity. At the same time, an introductory theoretical description of the phenomenon has been provided, showing a remarkable analogy with the dynamics of third-order Kerr microresonators. Here, we give an overview of our recent work on $χ^{(2)}$ frequency comb generation. Furthermore, we generalize the preliminary three-wave spectral model to a many-mode comb and present a stability analysis of different cavity field regimes. Although at a very early stage, our work lays the groundwork for a novel class of highly efficient and versatile frequency comb synthesizers based on second-order nonlinear materials.
