Terahertz radiation induced by coherent phonon generation via impulsive stimulated Raman scattering in paratellurite

M. Sotome, N. Kida, R. Takeda +1

We report on the observation of terahertz radiation in a non-centrosymmetric insulating oxide, paratellurite ($\alpha$-TeO${}_2$) by irradiation of a femtosecond laser pulse at room tempe…
