            "description": "This data set contains the data shown in the corresponding publication in Plasma Sources Science and Technology (https://doi.org/10.1088/1361-6595/acb815). This publication presents the first implementation of terahertz (THz) quantum cascade lasers (QCLs) for high-resolution absorption spectroscopy on plasmas. Absolute densities of ground state atomic oxygen were directly obtained by using the fine structure transition at approximately 4.75 THz. Measurements were performed on a low-pressure capacitively coupled radio frequency oxygen discharge. The results show that the presented method is well suited to measure atomic oxygen densities, and it closes the THz gap for quantitative atomic density measurements in harsh environments such as plasmas."
