摘要: The time and space resolved emission profiles of the CII line from laser-blow-off (LBO) plumes multilayered LiF-C thin film have been investigated using a laser-induced forward transfer technique. evolution features 426.7 nm were studied in different ambient environments ranging high vacuum to 3 mbar argon pressures at various fluences ablating laser. It was found that many plasma plume generated by LBO method resemble created conventional laser produced plasma; however, few differences observed their behaviour with regard splitting compression. A sudden change temporal profile occur distance about 4–6 mm away target. variation structures is reported. validity Rayleigh–Taylor instability, shock wave drag force model present experiment are also discussed.
