According to the review on the ecological impact by Cs-135, its nuclear transmutability and preceded isotope separation experiments on alkali metal Rb-85/87, isotope separation of Cs-133/135 by laser-chemical isotope separation method was discussed. Although high separation efficiency of 23.9 was obtained by a two cycle experiments on Rb-85/87, rather wide isotope shift between Cs-133 and Cs-135 will necessitate the application of doppler-free two-photon absorption method with further investigation of the Rydberg state and ionization.
