Peak emission of terahertz waves from (110)-oriented ZnTe by interacting phase-matched phonon resonances

O Hatem - JOSA B, 2019 - opg.optica.org
We demonstrate the measurement and assignment of phonon resonances responsible for
observed peak emission of terahertz (THz) waves from (110)-ZnTe. We show that optical …
