โœฆ Synopsis

Nitrogen atoms, as highly charged as N 5+, are found to be formed upon the irradiation of (NH3) . clusters with an intense femtosecond laser beam. Kinetic energy release values of the nitrogen atoms, from the Coulomb explosion of ammonia clusters, are found to be on the order of several hundred electron volts as calculated from the peak splittings, and also directly measured from cutoff potentials using a reflectron as an energy analyzer. Also, we observe a Coulomb explosion process which results in the production of intact cluster ions, and we propose a mechanism for their formation.

Iodine and argon ions, as highly charged as I"+ and A?+, are found to be formed upon the irradiation of HI clusters and HIAr, clusters with an intense femtosecond laser beam. Double peaks are observed for each multicharged species, and identified to result from Coulomb explosion of clusters. Kinetic

## Abstract Femtosecond laser is a potential tool for net shape processing of biodegradable polymers. However, laser processing of polymeric material is still a challenge and the effects induced by laser ablation needs to be investigated. Poly(__ฮต__โ€caprolactone) was micromachined at high fluence a
