摘要: This paper presents the high-order nonlinear spectrum of six-wave mixing (SWM) influenced by ionizing Rydberg atom environment in rubidium thermal vapor. The experimentally measured transmitted SWM signals reveal significant spectrum shifts and novel regularities, providing nonlinear spectrum insights into the ionization characteristics of Rydberg atoms. The detailed spectrum variations with increasing ion density are presented, paving the way for multi-wave mixing distribution of plasma and demonstrating SWM's potential as a tool for measuring the electric field induced by the ionization process.
