Increased interest in highly nonlinear glasses for use as Raman amplifiers has encouraged the development of an experimental apparatus to measure the material Raman gain coefficient on millimeter-thick bulk glass samples. Apparatus design considerations, details of the apparatus, and justification for the data analysis employed are provided. The apparatus is a powerful tool offering the ability to quickly screen glass samples over a wide range of compositions without the time and cost of fiberizing candidate materials into a guiding geometry to directly measure Raman gain.
