Laser induced impedance changes in a hollow cathode discharge containing sputtered uranium atoms were used for standard spectroscopic measurements, the determination of oscillator strengths, the measurement of the electron temperature of the discharge, isotope ratio analysis, and obtaining information about the sputtering process. Concentrations of uranium atoms as small as 10<sup>8</sup>/cc could be detected.
