Verification of Microfield Models Using Dense Laser Plasma Specta

Abstract: Optical properties of dense plasma depend on electric fields inside it (the so-called microfield). A critical survey is made of existing theoretical models of plasma microfields. The most important models are verified using experiments in which dense plasma was created by powerful laser radiation. It is shown that the Quasi-Independent Particle model (QUIP) provides the best theoretical verification and agreement with experiments. © 2021, Allerton Press, Inc.
