Asymmetric manipulations on the coherent Raman sideband generation under molecular modulations
P Yu, X Wu, Z Dong, J Chen, K Wang, L Wang, X Chen… - JOSA B, 2023 - opg.optica.org
We study the light evolution through a Raman-active medium, where a pair of fields pump
molecules near-resonantly and excite the molecular coherence. A synthetic lattice including …
