Selective nonlinear spectroscopy of inhomogeneously broadened phonon resonances in a disordered medium
Abstract
Panoramic Stokes and anti-Stokes scattering spectra have been measured in glass fiber lightguides with biharmonic monochromatic pumping. The results can be used to develop tunable narrow-band subnanosecond sources which emit in the Stokes and anti-Stokes spectral regions with respect to the pump. An arrangement for a selective stimulated-Raman gain is discussed. This arrangement has yielded the first measurements of the homogeneous broadening of an inhomogeneously broadened phonon vibration in amorphous SiO2.
