摘要

提出了一种利用多模激光二极管(MLD)产生亚太赫兹波的光混合技术。迄今为止，亚太赫兹光谱具有梳状结构，不适合应用于光谱学。我们通过在亚太赫兹区域的相互关联光谱中优化MLD光在photomixer上的光斑大小，成功地获得了宽背景下的改进光谱形状。

Improvement of spectral shape of sub-terahertz wave excited by multimode laser diode

A photomixing technique for sub-THz wave generation using multimode laser diode (MLD) has been developed. To date, sub-THz spectra had a comb structure that was not suitable for application to spectroscopy. We succeeded in obtaining the improved spectral shape with broad background by optimizing the spot size of the MLD light on the photomixer in a cross-correlation spectroscopy in the sub-THz region.
