Abstract

Isotope separation of ${^{203}{\rm Tl}}$ through pulsed laser optical pumping into the ${{\rm 6s}^2}{\rm 6p}\,{^2{\rm P}{^\circ _{3/2}}}$ meta-stable state, followed by pulsed laser ionization, has been theoretically studied through density matrix formalism. The efficiency of the isotope separation process has been compared with the cw laser optical pumping followed by pulsed laser photoionization reported earlier. The effect of peak power density, bandwidth and number density of atoms on the degree of enrichment and the production rate has been systematically studied. The optimum parameters for the efficient laser isotope separation ${^{203}{\rm Tl}}$ have been derived. It has been shown that using this method, it is possible to produce about 1.5 kg/y of  ${^{203}{\rm Tl}}$ isotope enriched to 90%.
