Foam targets have gained considerable importance over the last decade in laser–matter interaction. They find widespread applications such as inertial confinement fusion and secondary sources for particles radiation. At same time, advent of high repetition-rate laser systems, be they short-pulse tens femtosecond regime or kilo-Joule nanosecond regime, calls equally repetition rate targetry systems. A well-established system is tape target. In this article, we present successful marriage a...

Abstract High-power laser–matter interaction and the related high-energy density physics (HEDP) are two important topics in modern physics. However, for decades, a very restrictive limitation prevents researchers from studying these efficiently: nanosecond-kilojoule class lasers typically characterized by low repetition rate ( <?CDATA ${\approx}$?> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:mo>≈</mml:mo> </mml:mrow> </mml:math> 1 shot h −1 )...
