Abstract
Pulses with energy of 0.5 to 15 mJ and a repetition rate of 20 kHz from a Q-switched CO2 laser with continuous discharge were employed to dissociate32SF6 and12CF3I at 0.25 mbar. Gas exchange by diffusion is rapid enough to maintain isotopic selectivity. Dissociation yields agree with those measured at slightly raised temperature by a TEA laser. Because photons are cheaper from Q-switched lasers than from TEA lasers, economic consequences can result for isotope separation.
