2026-03-20 Probing High-Resolution Spectra with Scanning Raman Gain Modulated Dual-Comb Spectroscopy doi:10.57760/sciencedb.30811 en The preliminary work has proven that Raman gain modulation dual comb spectroscopy technology can effectively restore the mutual dryness of dual combs, eliminating the need for feedback locking or algorithm correction in dual comb spectroscopy. In addition, the Raman gain modulation process introduces additional degrees of freedom, such as the tuning capability of single frequency lasers. When tuning a single frequency laser, the longitudinal modes on the entire spectrum can be shifted as a whole, and real-time acquisition of the shift amount can achieve efficient and simple high-resolution spectral detection.  Raman gain modulation; dual-comb spectroscopy; high-resolution spectra Huang Shaowei Xiong Yatan Cheng Zhi Shi Yingjuan Cao Xinru Feng Yan Chen Dijun Liu Jiqiao Zhou Jiaqi Chen Weibiao PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
