In this paper, we reported the delay-time measurement experiments for a biased Semi-insulating Gallium Arsenide photoconductive antenna, triggered by laser pulse, and performed at the nonlinear model. The electromagnetic wave output character dependence of the delay-time is analyzed by using the Fourier transforms spectrum. The delay-time at the excited laser pulse of 532nm and 1064nm were measured. We observed a huge delay-time of hundreds microsecond when triggered by 1064nm laser at the specific biased-voltage conditions. The analysis indicated the huge delay-time relate to the photogenerated carriers translation between the different energy states of EL2 deep energy level..
