Claim 3:
4. The radio frequency laser according to claim 1, wherein the power box further comprises:
a top cover, wherein a first concave-convex structure is provided around an edge of the top cover; and
a frame, wherein two planes of the frame are connected to the top cover and the bottom plate respectively, a second concave-convex structure is provided on an outer edge on a side of the frame away from the bottom plate, and the second concave-convex structure is arranged around an outer edge of a top surface of the frame,
wherein the second concave-convex structure corresponds to the first concave-convex structure, and the first concave-convex structure and the second concave-convex structure form a radiation protection structure to attenuate an intensity of an electromagnetic radiation overflowing through a gap between the edge of the top cover and a top end of the frame.
