Abstract (in Japanese) (See Japanese page) 
(in English) As an evaluation of ultrafast carrier dynamics in electronic materials, a terahertz emission from materials has been proposed. In this study, we have constructed a new system combining a pump-probe technique utilizing a femtosecond pulse laser with a laser terahertz emission microscope (LTEM). The developed pump-probe laser scanning terahertz emission microscope (PP-LTEM) enables us to evaluate local carrier dynamics in materials, and images carrier distribution in a time resolution. We have measured a dipole antenna fabricated on InP in this system, and obtained terahertz emission images in a subpicosecond time-resolution.
