Femtosecond laser interactions with methyl iodide clusters.

Multiple ionization of CH3I clusters by nanosecond laser: Electron energy distribution and formation mechanism of multiply charged ions

“…Recently, the interaction of nanosecond laser with CH 3 I cluster was investigated widely, where multiply charged ions with high energy were observed experimentally [4][5][6][7]. Luo et al investigated the interaction of nanosecond laser with CH 3 I in diffused beam and pulsed beam by a time-of-flight mass spectrometer [8].…”

“…Vatsa and co-workers investigated the interaction of nanosecond laser pulse with tetramethyl silane (Si(CH 3 ) 4 ) clusters for the generation of multiply charged silicon and carbon ions. And their results obtained agreed qualitatively with the model proposed earlier [11].…”

Cluster-assistant generation of multiply charged atomic ions in nanosecond laser ionization of seeded methyl iodide beam

“…Methyl iodide (CH 3 I) has been chosen in this experiment as it has been extensively studied in the past and is still the subject of many studies in recent years [18][19][20][21][22][23][24][25][26][27][28][29][30]. Recently, Graham et al [25] reported the study of the multielectron dissociative ionization (MEDI) processes induced by 50 fs strong laser at 10 16 W/cm 2 .…”

“…Lots of works about traditional MPI have been done under a laser intensity of 10 6 -10 9 W/cm 2 [19,21], and recent works about high intensity laser field and molecules were done under a laser intensity of 10 13 -10 17 W/cm 2 by picosecond and femtosecond lasers [25][26][27][28][29][30]. Recently, we reported the generation of C q+ (q = 2,3) in photoionization of benzene seeded in argon by 25 ns, 532 nm pulses from a YAG laser at intensity about 10 11 W/cm 2 [31].…”

Cluster assistant generation of C2+ and C3+ ions in nanosecond laser ionization of seeded benzene beam

“…The observation of neutrons from deuterium clusters indicated that nuclear fusion can occur in the plasma formed after cluster exploding [4]. Now, the observation of highly charged atomic ions produced by intense laser beams has been extended to molecular ions [9][10][11][12][13][14]. At high laser intensities, the strong electric field can excess the molecular Columbic field.…”
