Abstract :
Intense monocycle THz pulse can drive large-amplitude vibration mode which gives us a chance to perform novel THz nonlinear spectroscopy. We experimentally demonstrated large amplitude anharmonic intermolecular vibration mode using intense monocycle THz pulse. We performed the nonlinear transmission spectroscopy of the amino acids micro-crystals at different electric field amplitude and observed the nonlinearity of vibration spectrum.
