Spectroscopic diagnostics of plasma interaction with an external oscillatory field

摘要: The paper presents an advanced analysis of the experimental Al Heβ emission from aluminium plasma created by one ps-laser beam and then subjected to another when pulse first laser was already off. has two equally important goals. goal is present overview general principles spectroscopic diagnostics plasmas containing a quasi-monochromatic electric field (QEF) clarify some erroneous/confusing statements in theoretical literature. second model signatures strong QEF caused thus provide adequate interpretation spectral line profiles. been achieved via simulations coupling code based on Floquet–Liouville formalism with particle-in-cell kinetic that provides spatial distribution plasma. In this way—by using ultra-high resolution K-shell spectroscopy—the established link between research communities: dealing laser–plasma interactions other atomic processes plasmas.
