Investigating plasma behavior in liquid jets via supercontinuum light is vital for understanding its physics and industry applications. This study employs time-resolved experiments with a double-pump configuration to examine plasma formation mechanisms. Supercontinuum light, generated by focusing an 800 nm pump beam onto a quartz plate, serves as the probe directed towards the plasma. Analysis of transmitted pulses offers insights into plasma dynamics across wavelengths. Experiments on an isopropyl liquid jet revealed plasma behavior and its impact on transmitted wavelengths over time delays between pump pulses. These findings elucidated plasma relaxation and degradation mechanisms, supplemented by a theoretical model estimating plasma refractive index.
