Visualization of plasma-induced processes by a projection system with a Cu-laser-based brightness amplifier

摘要

A novel method for visualization of the process of interaction of high-power energy fluxes with various surfaces is proposed. The possibility of the dynamic visualization of a surface covered with a ~3-cm-thick plasma layer with a linear density of ~10~(16) cm~(-2) is demonstrated experimentally. A scheme of intracavity shadowgraphy of phase objects with the use of a laser projection microscope is developed. Shadow images illustrating the development of the plasma torch of an erosion capillary discharge in air are presented.
