RESONANT RAMAN SCATTERING OF 23 cm-1 PHONONS BY Dy3+ IONS IN LaF3

Abstract
The lifetime of 23 cm-1 phonons in LaF3 is reduced from 600 ns to 125 ns when the transitions within the 6H15/2 ground manifold of Dy3+ are tuned with a magnetic field into resonance with the 23 cm-1 phonons. Our analysis suggests that the reduced lifetime results from Raman scattering of the 23 cm-1 phonons to lower energy by an amount equal to the energy difference between the two lowest Dy3+ levels.
