摘要

为了推进基于太赫兹（THz）参数生成的实时光谱学，我们实现了十多个太赫兹波长的同时生成。我们使用在非线性光学晶体内通过级联过程在多个波长产生的高阶斯托克斯光束作为太赫兹参数产生的泵浦和种子光束。这允许并发产生高达13太赫兹波长。这有利于各种试剂的实时光谱分析。在1-2太赫兹范围内同时产生13太赫兹波长的能力极大地帮助了试剂识别，尽管存在障碍物，并在未来的光谱应用中具有重要的潜力。

Multiwavelength Terahertz Parametric Generation Using Higher Order Stokes Beams

To advance real-time spectroscopy based on terahertz (THz) parametric generation, we achieved the simultaneous generation of more than ten THz wavelengths. We used higher order Stokes beams generated at multiple wavelengths via a cascaded process within a nonlinear optical crystal as both the pump and seed beams for THz parametric generation. This allowed concurrent generation of up to 13 THz wavelengths. This facilitated real-time spectroscopy of various reagents. The ability to generate 13 THz wavelengths in the 1–2 THz range simultaneously greatly aids in reagent identification despite the presence of obstructions and holds significant potential for future spectroscopic applications.
