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.\u003C\/p\u003E\n","url":"https:\/\/www.inptdat.de\/dataset\/terahertz-absorption-spectroscopy-measuring-atomic-oxygen-densities-plasmas-dataset","state":"Active","log_message":"Update to resource Terahertz absorption spectroscopy for measuring atomic oxygen densities in plasmas - Fig. 8","private":true,"revision_timestamp":"Mon, 02\/06\/2023 - 21:55","metadata_created":"Mon, 01\/16\/2023 - 15:14","metadata_modified":"Mon, 02\/06\/2023 - 21:55","creator_user_id":"0e27023c-5517-4b3f-b96e-c939dc6a74ff","type":"Dataset","resources":[{"id":"15a4c673-edf0-42de-bed2-43de8d7cd911","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node672_figure2.csv","description":"\u003Cp\u003ESimulated transmission spectra (T = 296 K) of ammonia and atomic oxygen from the HITRAN spectral database (\u003Ca href=\u0022https:\/\/doi.org\/10.1016\/j.jqsrt.2021.107949\u0022\u003Ehttps:\/\/doi.org\/10.1016\/j.jqsrt.2021.107949\u003C\/a\u003E).\u003C\/p\u003E\n","format":"csv","state":"Active","revision_timestamp":"Fri, 02\/03\/2023 - 15:33","name":"Terahertz absorption spectroscopy for measuring atomic oxygen densities in plasmas - Fig. 2","mimetype":"text\/csv","size":"548.79 KB","created":"Thu, 02\/02\/2023 - 17:49","resource_group_id":"8213480c-adb6-4936-8811-f1dd8f8b3a2f","last_modified":"Date changed  Fri, 02\/03\/2023 - 15:33"},{"id":"08f45edc-72ea-4e6c-b442-01ff1bb076a3","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node672_figure3.csv","description":"\u003Cp\u003ERaw spectrum from a simultaneous measurement of a reference gas cell with NH3 (p=2 mbar, L=15 cm) and an O2 plasma (p=1.3 mbar, P=30 W), measured with a laser temperature of 44.30 K.\u003C\/p\u003E\n","format":"csv","state":"Active","revision_timestamp":"Fri, 02\/03\/2023 - 15:33","name":"Terahertz absorption spectroscopy for measuring atomic oxygen densities in plasmas - Fig. 3","mimetype":"text\/csv","size":"1.71 MB","created":"Thu, 02\/02\/2023 - 17:53","resource_group_id":"8213480c-adb6-4936-8811-f1dd8f8b3a2f","last_modified":"Date changed  Fri, 02\/03\/2023 - 15:33"},{"id":"5b755e26-5a63-4e1b-94df-3698e3e979ad","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node672_figure4.csv","description":"\u003Cp\u003EComparison of the absorption spectra of a reference gas cell with NH3 (p=0.01 mbar, L=3 cm), showing the sR(7,3)-transition of 14NH3 at 158.214792 cm-1, for different laser tuning speeds and a laser temperature of 54.45 K.\u003C\/p\u003E\n","format":"csv","state":"Active","revision_timestamp":"Fri, 02\/03\/2023 - 15:33","name":"Terahertz absorption spectroscopy for measuring atomic oxygen densities in plasmas - Fig. 4","mimetype":"text\/csv","size":"1.17 MB","created":"Thu, 02\/02\/2023 - 17:57","resource_group_id":"8213480c-adb6-4936-8811-f1dd8f8b3a2f","last_modified":"Date changed  Fri, 02\/03\/2023 - 15:33"},{"id":"794d9922-dceb-4b45-a5fb-c8ac302f5f08","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node672_figure5.csv","description":"\u003Cp\u003ESpectral absorption profile of the sR(7,3)-transition of 14NH3 at 158.214792 cm-1, measured in a reference gas cell with NH3 (p=0.01 mbar, L=3 cm) using a laser tuning speed of 100 mA\/s and a laser temperature of 54.45 K.
