Combining Laser‐Induced Breakdown Spectroscopy and Raman Spectroscopy: Instrumentation and Applications

Raman spectroscopy and laser-induced breakdown spectroscopy (LIBS) are two techniques becoming increasingly popular in modern analytical chemistry applications due to their unique capability for express analysis of any sample type in any environment. This chapter describes the basics on how to integrate both LIBS and Raman spectroscopy techniques into a single instrument. It reviews numerous applications for combined Raman and LIBS techniques. Both Raman spectroscopy and LIBS techniques are based on light–matter interaction, but the fundamental physical processes are different. The sensitivity of integrated Raman–LIBS instrument strongly depends on collecting optics efficiency. Raman spectroscopy technique became a well-recognized technique for cultural heritage and archaeology studies due to high selectivity and the nondestructive nature of Raman analysis. Combined Raman and LIBS measurements are prospective for the express and/or remote identification of bio-materials in the inorganic environment for biological and medical purposes, forensic applications, and extraterrestrial rover exploratory missions.
