We have observed isotopically selective diode laser-excited optogalvanic effects in uranium at 778.42 and 776.10 nm. The samples were natural abundance uranium oxide, as well as depleted (0.3% {sup 235}U), natural (0.7% {sup 235}U) and enriched (9.75% {sup 235}U) uranium metal or powders. The measurements were carried out in a demountable-cathode glow discharge cell. Preliminary evaluations of precision for uranium isotopic ratios measured using this technique suggest that it should have broad analytical applications for uranium and other amenable actinides or lanthanides. {copyright} 1995 {ital American} {ital Institute} {ital of} {ital Physics}
