| Research Abstract |
We have demonstrated a new laser isotope separation method utilizing molecular rotational coherence. In the demonstration, isotope selective ionization for a gas mixture of nitrogen isotopologues (^<14>N_2 and ^<15>N_2) has been realized by two-pulse irradiation of femto second laser, indicating that the present method is applicable as an isotope separation method. Additionally, we have tested the following two subjects, to improve the isotope selectivity and to examine the possibility for heavy isotopes. (1) A pulse-train irradiation of femto-second laser pulses for the molecular alignment, and (2) optimization of the gas jet conditions.
