Paper Abstract

Recently, much attention has been focused upon generation of ionized particles from solid target by coulomb explosion using high intensity and ultrashort pulse laser since the high intensity electric field can easily ionize to the maximum charge of the element. This paper reports the generation of molecular carbon ions and decrease of multiple charged ions in case of irradiation of low power nanosecond laser pulse prior to femtosecond laser pulse. The changes in the ion current waveform have been analysed by time of flight measurement with 76.4cm of drift section. This observed waveform was interpreted using energy conservation law.
