Abstract
Monochromatic phonons are generated in LiYF4:Pr3+ using defect induced one phonon absorption (DIOPA) of far infrared radiation. Phonons are detected in a time resolved, frequency selective manner using an absorption vibronic sideband spectrometer. The combination of these techniques enable us to investigate the complete spectral and temporal evolution of the decay products of the monochromatically generated nonequilibrium phonon distributions.
