Organic nonlinear optical (NLO) crystals are among the most efficient (>1%) terahertz (THz) radiation generators. However, one of the limitations of using organic NLO crystals is that the unique THz absorptions in each crystal make it difficult to ob

We combine THz pulses from two complimentary crystals to increase peak field strength and create a broad, smooth spectrum. We show the utility of using this strong THz pulse to nonlinearly excite vibrations in solids.

We present our method for creating first-principles models of two-dimensional (2D) terahertz spectra in solid materials. We demonstrate the accuracy of these models and their exciting potential in the growing field of nonlinear phononics.
