Atomic terahertz-vibrations solve the enigma of ultrashort soliton molecules

Journal Reference: Alexandra Völkel, Luca Nimmesgern, Adam Mielnik-Pyszczorski, Timo Wirth, Georg Herink. Intracavity Raman scattering couples soliton molecules with terahertz phonons. Nature Communications, 2022; 13 (1) DOI: 10.1038/s41467-022-29649-y In ultrashort-pulse lasers, optical solitons can form particularly tight spatial and temporal bonds. These are also called ultrashort “soliton molecules” because they are stably coupled to each … Read more
