Shadowgraphy of pulsed CO laser ablation of polymers

Heavy plume expansions in air, helium and argon produced by pulsed CO2 laser ablations of poly(methyl methacrylate) (PMMA) and polyimide (PI) were imaged by shadowgraphy. The PMMA was melted at 1-2 mm depth beneath the surface followed by an outward expulsion of heavy plumes. A shock front was forme...
