Overview of Raman Sepctroscopy


In this interview, Wavelength Electronics Inc. joins Kevin Repasky, Ph.D., Assistant Professor at Montana State University, a previous researcher of Raman scattering. Currently, his research group is focusing on atmospheric LiDAR and DIAL. Topics discussed include research, critical parameters, electronic control, and a comparison of Raman to other types of spectroscopy.

Raman spectroscopy can be a practical way to identify and quantify different types of molecules based on Raman scattering. Understanding the scattering cross-section and frequency shift of the appropriate molecules ensures experimental success. As this interview shows, stable control of a laser diode, whether as the light source or pump laser, is crucial in establishing stable wavelength and reduced electrical and optical noise.
