“Copropagation and Spiraling Oscillation of Two Relativistic Laser Beams in a Plasma Channel for Controlled Coupling”

https://pubmed.ncbi.nlm.nih.gov/38115536

The copropagation of two relativistic laser beams in a plasma channel can result in their centroids spiraling and oscillating, and this phenomenon can be used to control the coupling of intense lasers in plasma for various applications.
