Paper Abstract

Generation of the multiply charged ions and molecular ions have been investigated using synchronous irradiation of high intensity and ultrashort pulse of Ti:sapphire laser and fourth harmonics of Q-switched nanosecond pulse of Nd:YAG laser to carbon target. The ion current wave forms have been analyzed by means of the time-of-flight mass measurement. The formations of cluster ions were detected due to the irradiations of both high intensity and ultrashort pulse of Ti:sapphire laser and fourth harmonics of Q-switched nanosecond pulse of Nd:YAG laser.
