Raman System Enhancements for Materials Characterization in Energy Geoscience

The Kentucky Geological Survey (KGS) is acquiring a Horiba LabRAM Odyssey Raman microscope with a 532 nm laser included in its standard configuration. To enhance the system, we request funding to add a 785 nm laser. This near-infrared laser will substantially improve our Raman capabilities by minimizing fluorescence interference, a critical factor when analyzing samples prone to fluorescence under shorter wavelengths. The 785 nm laser also offers deeper penetration into samples, facilitating analysis of inclusions. This expanded wavelength range will allow us to conduct advanced studies that are not feasible with the 532 nm laser alone. Additionally, we seek critical accessories to ensure optimal operation of the system, which will be funded by KGS cost-share. These include an optical table, which will provide a vibration-free platform critical for precise Raman measurements, and a microscope enclosure for laser safety and ambient light control. We also aim to acquire accessories to integrate the system with our existing Linkam heating-freezing stages, enabling the analysis of samples under non-ambient temperatures. These components will create a stable, secure, and versatile environment for high-performance Raman spectroscopy. By integrating the 785 nm laser and these accessories, we will establish a state-of-the-art Raman spectroscopy facility capable of addressing complex research questions in energy and materials geoscience studies. This capability will position our lab and the greater UK community to compete for larger-scale funding opportunities, such as those from the Department of Energy, the National Science Foundation, and industry, thus expanding our research impact and advancing critical scientific goals.
