A holographic detection device for a content of a gas in a GIS switch includes a laser and a data process system. The laser includes a laser emitter and a laser receiver which are fixed at a sampling port of the GIS switch and connected with the data process system. A holographic detection method for a content of a gas in a GIS switch includes emitting a laser beam towards the inside of the GIS switch; receiving the laser beam from the inside of the GIS switch, and calculating a content of hydrogen fluoride gas inside the GIS switch according to an intensity of the emitted laser beam and an intensity of the received laser beam. Since the laser beam goes through the inside of the GIS switch, there is a small error in the detection result, which thus can reflect a real state inside the GIS switch.
