Laser pulse shape manipulation can serve as an efficient tool for selective quantum level population control. In this paper it will be
demonstrated parametrization of laser pulse shape, parameters variation of which can be implemented by an optical mask applied
to the seed pulse. Its further amplification is provided by subsequent cell filled by CO2 laser medium, the output laser pulse is subject
to use in the method of isotopes separation by selective retardation of condensation in overcooled gas flow(SILARC), for selective
excitation of all four chlorine isotopologues of 11BCl3 with small time delays, corresponding to respective levels population build up
times. It is acheieved by that laser pulse emission spectrum has modes matching absorption lines of different chlorine isotopologues
in 11BCl3. In order to provide the largest interaction volume of gas flow with laser beam, the latter should intersect it as many times
as possible and ambient gas pressure should be maintained on the level, such that gas flow remains planar over all its extension from
the nozzle outlet to the skimmer inlet. In order to save expensive laser photons, we assume, that reflectivity of mirror walls is very
high and resonator condition inside irradiation cell is fulfilled. Comparison of our results for enrichment factor and product cut
time evolution with one mode continuous excitation indicates that pulsed irradiation with specifically designed laser pulse shape
allows to increase extractable per cycle isotope quantity significantly at the same energy expenses. Calculations were carried out
at the temperature and initial laser intensity, corresponding to the maximum of isotope production over gas flow transition time
across irradiation cell. Gas flow static pressure and BCl3 molar fraction in carrier gas-argon are chosen to fixed at some small values
minimize isotope scrambling.
