Abstract：  As an indispensable and fundamental facility in modern society， power grid emphasizes the utmost important factors of continuity and safety operation. To ensure stable operation and promote rapid development of smart grid， it is particularly important to implement real-time monitoring of the power grid. Here an AC field-coupled laser device was proposed for voltage detection. The device has an electrode/laser diode/electrode structure， which enables non-contact monitoring by converting the information of the high-voltage lines into modulated laser pulses. Experimental results show that the optimal linear fitting R 2 is 0.99364 for the peak intensity of the output laser waveform in the proposed laser device structure， which confirms it can accurately extract real-time voltage variations on the HV line. The laser intensity output waveform and the voltage waveform of the HV test bar have strong correlation both in time and frequency domains， which enable rapid capture of the voltage variation and provide instantaneous response. As a new online monitoring device for the high-voltage lines， this laser structure can provide a new impetus for the development of power grid technology.
