THz QCL-Based Cryogen-Free Spectrometer for in Situ Trace Gas Sensing

THz QCL-Based Cryogen-Free Spectrometer for in Situ Trace Gas Sensing

We report on a set of high-sensitivity terahertz spectroscopy experiments making use of QCLs to detect rotational molecular transitions in the far-infrared. We demonstrate that using a compact and transportable cryogen-free setup, based on a quantum cascade laser in a closed-cycle Stirling cryostat,...
