摘要：

Terallertz (THz) wave generation in a periodically poled Mg:LiNbO3 crystal was detected by a pump-probe technique and analyzed using frequency and time-frequency spectra. Multifrequency THz waves were clearly observed, providing information about the domain structure of the crystal. A theoretical T-function model was used to fit the frequency spectrum. A method that can characterize the detailed domain Structure and THz capabilities of the inner crystal's parts is proposed. (C) 2009 Optical Society of America
