Abstract
In this paper performance of 13C molecular laser isotope separation is reported. For this purpose, a TEA CO2 laser pumped NH3 laser was constructed which provides output energies of
350-400mJ with a pulse duration of 100 ns at 12.812µm wavelength. The laser pulses were focused into an irradiation cell containing 0.1-1 mbar CCl4 gas pressure. Under the multiphoton dissociation condition of 12CCl4, a maximum selectivity of S=4 and separation factor of β=7 was obtained.
