Dissertation note: Thesis (M.Sc.) - Cairo University - National Institute Of Laser Enhanced Sciences - Department Of Laser Application In Physics Summary: A comparative study between single and double pulse - laser induced breakdown spectroscopy (LIBS) was performed on n - type silicon (111) targetA new mobile double pulse Nd : YAG laser at 1064 nm was used throughout the measurementsThe experiment was carried out in two ambient gases ; air and argon at different pressures of 07 , 470 and 1000 hPa in air and 470 and 1000 hPa in argonThe ambient gas interacts with the laser beam and the plume , several mechanisms are involved in these interactions , such as , plasma shielding , shock wave production and plasma expansionPlasma shielding effect reduces laser - material coupling efficiencyHowever , the induced shock waves increase the coupling efficiency in case of double pulse LIBS
