A wide band electro-optic modulator is presented which allows the frequency calibration of Brillouin spectra over the frequency range from a few MHz up to ≈40 GHz, a range spanning Brillouin light scattering from condensed matter. Measurements of both frequency and the linewidth of Brillouin peaks relative to longitudinal acoustic modes of water using the electro-optic modulator as a frequency reference are presented. © 2001 American Institute of Physics.

Abstract
A wide band electro-optic modulator is presented which allows the frequency calibration of Brillouin spectra over the frequency range from a few MHz up to ≈40 GHz, a range spanning Brillouin light scattering from condensed matter. Measurements of both frequency and the linewidth of Brillouin peaks relative to longitudinal acoustic modes of water using the electro-optic modulator as a frequency reference are presented. © 2001 American Institute of Physics.File in questo prodotto:
