Nonlinear distortion of intense THz beams
Near- and far-field beam profiles were measured for THz pulses generated in LiNbO _3 by optical rectification of 200 fs pulses with a tilted pulse front. The variation of the THz beam size and a dramatically increasing divergence angle with increasing pump fluence were observed in the (horizontal) p...
