Abstract
Systematic and reproducible methods of evaluating fiber-optic probes and laser sources for Raman spectroscopy have been developed. We have investigated the performance of two different types of external cavity diode laser sources for Raman spectroscopy. These lasers were evaluated in terms of long-term wavelength drift and power stability. Experimental methods and computer-generated models were developed to evaluate fiber-optic Raman probe performance under a variety of conditions and for a variety of sample types. Performance parameters investigated include probe sensitivity, sampling volume, and discrimination against fiber-optic silica background. Sample types studied include clear liquids and solids, highly scattering solids and slurries, and highly absorbing liquids and solids.
