Terahertz absorption spectroscopy for measuring atomic oxygen densities in plasmas - Dataset
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.
