description The invention provides a laser discharge cavity inner surface coating structure and a preparation method thereof. The laser discharge cavity inner surface coating structure comprises an inner coating laid on the inner surface of a discharge cavity body; the outer plating layer is laid on the outer side of the inner plating layer; the inner plating layer is a Ni-Cu-P plating layer; and the outer plating layer is a Ni-P plating layer. According to the invention, a Ni-Cu-P/Ni-P double-layer amorphous coating is plated on the inner surface of a cavity body of a laser discharge cavity through a chemical nickel plating technology. And due to the existence of the Cu element in the plating layer, the surface of the plating layer is uniform and compact, the porosity of the plating layer is reduced, and therefore the corrosion resistance of the plating layer is enhanced. And moreover, due to the fact that the rare earth elements can inhibit crystal nucleus growth and H2 precipitation, the Ni-P coating doped with the mi
