We present a new method for producing multiply-charged actinide molecules. Using pulsed laser ablation of micro-targets, we generate ThF_xⁿ⁺ (x = 0-3, n ≤ 3) from ThF₄ salt, and UOⁿ⁺ from metallic uranium up to UO⁴⁺. The production of ThF²⁺ and UO³⁺ is particularly relevant for searches for nuclear Schiff moments, while UO⁴⁺ approaches the limit of chemical stability. Relativistic density-functional calculations validate the observed charge states and molecular structures. The technique provides access to a broad range of multiply-charged radioactive molecules for a variety of future precision experiments.
