Engineering Physics Annotation << Back Investigation of laser-induced optical discharges with ablating wall dynamics and macrostructure E.Yu. Loktionov, Yu.Yu. Protasov Laser-induced optical discharges with ablating polymer ((C2F4)n, (CH2O)n) wall dynamics and macrostructure experimental investigation results are presented. Data obtained using high-speed shadow-, schlierengraphy, laser interferometry and emission spectroscopy. Spatial and temporal fields of electron number density; shock wave velocity, pressure and temperature; laser pulse energy to shockwave energy conversion ratio are evaluated. Near-surface gas-plasma flows macrostructure, laser regulation parameters and target chemical composition influence are analyzed. Key words: optical discharges, shockwaves, polymers, flow macrostructure. E-mail: stcpe@bmstu.ru
