    Ultraviolet spectral broadening by stimulated rotational Raman scattering on nitrogen pumped with signal laser injection by Xiangbing Wang, Xiangxu Chai, Ping Li, Bo Zhang, Qihua Zhu, Xiaocheng Tian, Ju Wang, Zhaoyu Zong, Song Zhou, Ke Yao, Sen Li, Junpu Zhao, Zhitao Peng

    Published 2025-01-01
    “…Theoretical calculations show that 2% bandwidth spectral broadening can be achieved by injecting 20 kW/cm2 signal light at 2.2 GW/cm2 flux of the pump laser. In addition, high-frequency modulation in the near field can be effectively avoided through replacement of the original random noise signal light by the controllable signal light. …”
