Abstract
Spatially and temporally resolved measurements of transmitted laser radiation, radial density profiles, and plasma dynamics indicate beam self‐trapping in CO2 laser‐induced helium plasmas in strong longitudinal magnetic fields. Trapping is observed for the cases of β≳1, β?1, and β<1. Longitudinal plasma growth occurs principally by breakdown waves and weak radiation‐supported detonation waves.Keywords
