The cost reduction in the production technology of microsatellites necessitates the use of simple and inexpensive engines, and the ablation pulsed plasma microthruster (μPPT) meets these requirements well due to its simple design. The research and optimization of processes in μPPT are divided into two main areas: the optimization of electrical circuits and the optimization of working processes in the discharge chamber, one of the most important of which is the evaporation of the propellant under the action of high-intensity broadband radiation. This article presents the results of an experimental study of the light erosion and parameters of the resulting plasma of fluoroplastic \({\left({C}_{2}{F}_{4}\right)}_{n}\) (the most common propellant for ablation pulsed plasma microthrusters) under the irradiation of the fluoroplastic surface with powerful broadband UV-VUV spectrum radiation. A magnetoplasma compressor discharge of the erosion type (MPC) was used as the radiation source. The energy and spectral composition of the discharge radiation were varied by changing the background gas and the distance between the discharge cell and the irradiated samples. Two-exposure laser holographic interferometry and Schlieren photography were used for the diagnostics and visualization of gas-dynamic structures. The authors discuss that with equal energy input into the discharge, the evaporation dynamics is determined by the spectral range of the radiation (energy of the radiation quanta).
