摘要：

We present a sensitive imaging method capable of the selective characterization of the nonlinear THz beam profile, providing a direct handle to optimize chi ((3)) light -matter interactions that are critical to two-dimensional (2D) THz spectroscopies. In particular, this method facilitates the development of experimentally challenging 2D THz spectroscopies with multiple THz emitters, which enables direct investigations of fast picosecond dynamics in liquids and solids that are challenging in single-emitter 2D THz spectroscopic setups.
