In twinned LaAlO3, the 1.1 THz Eg Raman phonon is excited by a two-photon THz process, while the 0.86 and 0.36 THz oscillations are propagation artifacts, not phonons.

Disentangling Electronic and Ionic Nonlinear Polarization Effects in the THz Kerr Response of LaAlO$_{3}$
In twinned LaAlO3, the 1.1 THz Eg Raman phonon is excited by a two-photon THz process, while the 0.86 and 0.36 THz oscillations are propagation artifacts, not phonons.
