Evaluation of two-dimensional terahertz emitters for scanning laser terahertz imaging system using 1.56 #x03BC;m femtosecond fiber laser

摘要

We evaluatetd a GaAs<110> substrate as a two-dimensional (2D) terahertz (THz) emitter by using a recent-fabricated scanning laser terahertz imaging system. As a result, we could observe a certain THz radiation available to a 2D THz emitter plate.
