Abstract

In this paper, a 10~15 na duration (FWHM), 0.2~0.4 J energy 002 laser pulse is generated by a tunable pulse TEA CO2 laser and a plasma shutter. Using this pulse, multiple-photon dissociation (MPD) of trifluoromethane at 200Torr resulted in well selective dissociation and 7600+1000-1500-fold single-step deuterium enrichment.
