Laser diagnostic methods are developed to study the behavior of laser‐ablated zirconium carbide (ZrC). The optical emission spectra from the Zr‐C plasma plume is measured from 200 to 500 nm. Emission from zirconium atoms dominated the observed spectra. From the spectra, the average plasma temperature was estimated to be 10500 ± 1500 K. Plume formation is characterized using a CCD camera to capture emission at delay times (with respect to the ablation laser pulse) ranging from 1 μs to 1 ms and using planar laser‐induced fluorescence to map Zr atom distributions.
