Abstract A brief review on laser separation of rare ytterbium and palladium isotopes by selective photoionisation is presented. The {sup 168}Yb isotope enrichment is performed using the optical scheme proposed by A.M. Prokhorov and co-workers in 1991. The kinetic model of selective photoionisation is described in detail and the production of highly enriched {sup 168}Yb isotopes in weight quantities is reported (up to 90 % - 95 % in a plasma, up to 62 % on a collector, and up to 45 % in a wash solution). The rate of production of enriched ytterbium achieves 5 - 10 mg h{sup -1} (more that 1 g per month). The results of theoretical and experimental studies of selective photoionisation of palladium are also presented. A substantial enrichment of different palladium isotopes is achieved: {sup 102}Pd - up to 18 % (the natural content is 1 %), {sup 104}Pd - up to 70 % (11.4 %), and {sup 105}Pd - up to 60 % (22.33 %). The kinetics of selective ionisation of palladium is analysed using new experimental data on the fine structure and hyperfine splitting of the terms.
