Detection of laser-induced fluorescence simultaneously with an optogalvanic signal in a hollow-cathode discharge provides information about the laser-atom interaction that leads to the optogalvanic effect, resulting in a better comprehension of its spectroscopic applications. Because of the high density of levels in heavy atoms, multiphoton transitions can easily occur and complicate the interpretation of saturation effects. The representative case of the 5915-A uranium transition is reported.
