Compact, Coherent, and High-Power THz Sources and Applications

Abstract

Within the last 12 months of the grant period, we had used our FTIR acquired from Bruker Optics via a DURIP grant to measure the transmission spectra of a few diatomic and triatomic molecules. As a result, we had observed distinct ro-vibrational and rotational transitions in carbon monoxide isotopic variants, nitrogen dioxide, and carbon dioxide. Furthermore, we had used the widely-tunable monochromatic THz source developed by us to measure the spectra of the same four molecules. We would like to note that the spectral measurements in the mid-IR and THz regions are essential to the accurate determination of rotational constants. Following our results, the transition frequencies measured by using two methods are quite consistent with each other.
