High-electric-field-intensity terahertz pulse generation platform adaptive to insulation space charge ellipsometry detection system

The invention discloses a high-electric-field-intensity terahertz pulse generation platform adaptive to an insulation space charge ellipsometry detection system. The platform is composed of a femtosecond laser source, a photoconductive antenna, a sulfur hexafluoride closed gas chamber and a bias voltage source, the sulfur hexafluoride closed gas chamber is additionally arranged on the periphery of the photoconductive antenna so that the maximum imposable bias electric field of the photoconductive antenna can be improved, meanwhile, the parameters of the femtosecond laser, the photoconductive antenna and the bias voltage source are regulated and controlled, and the sensitivity of the femtosecond laser is improved. The terahertz pulse electric field intensity is improved. Based on the platform disclosed by the invention, high-electric-field-intensity terahertz pulse generation can be realized, and the generated terahertz pulse can realize effective disturbance on insulation space charges. 本发明公开了一种适配绝缘空间电荷椭偏探测系统
