Narrow Linewidth Lasers for Brillouin Light Scattering Spectroscopy

Nonlinear optical effects are exploited in a wide range of technologies. In particular, two common nonlinear inelastic scattering methods, Raman and Brillouin scattering, both give important insight into the physical properties of the material under investigation. While Raman spectroscopy reveals the structure or chemical composition, Brillouin spectroscopy provides information on a larger scale such as the elastic or magnetic properties.

In this application note we demonstrate that the fixed wavelength diode pumped Cobolt Calypso laser at 491 nm as well as the cw single frequency tunable light source C-WAVE, are suited to the demanding technique of Brillouin spectroscopy
