2D measurement and spatio-temporal coupling of few-cycle THz pulses.

The propagation of few-cycle THz pulses are measured by the improved CCD based 2D THz imaging system. There exists strong spatio-temporal shaping effect, leading to dramatically time dependent beam diameter and wave front. Theoretical simulation is given.
