Parabolic mirror-enhanced Raman spectroscopy enables high-sensitivity trace gas detection

A research team led by Prof. Fang Yonghua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences proposed and systematically optimized a novel parabolic mirror cavity-enhanced Raman spectroscopy (PMCERS) technique, achieving a marked improvement in gas detection sensitivity through the integration of advanced optical design and signal processing methods. These results were published in Optics & Laser Technology.
