Utilizing NH3 Laser Pulses in Multiphoton Dissociation Process of CC14 Molecules with 13C Isotope Selectivity

In this paper performance of 13C molecular laser isotope separation is reported. For this purpose, a TEA C02 laser pumped NH3 laser was constructed which provides output energies of 350-400mJ with a pulse duration of 100 lis at 12.812(im wavelength. The laser pulses were focused into an irradiation cell containing 0.1-1 mbar CCI4 gas pressure. Under the multiphoton dissociation condition of 12CC14, a maximum selectivity of S=4 and separation factor of P=7 was obtained.
