Orbital angular momentum impact on light scattering by phonons tested experimentally

Orbital angular momentum impact on light scattering by phonons tested experimentally

Polarized Raman spectra of piezoelectric bismuth germanate single crystal were recorded using vortex light in order to verify the predicted symmetry selection rules for Raman scattering of photons with nonzero orbital angular momentum. First, the phonon spectrum is fully characterized by the infrare...
