Rare earth materials have rich spectra due to its rich energy levels. With the transition of energy levels of the rare earth materials,1.06 μm laser stealth and other waveband stealth can be achieved. The preparation technology of materials containing samarium is introduced,and the influence of different crystal forms,different grain sizes and different dopings on the reflectivity for 1.06 μm laser is discussed. Yttrium oxide,materials containing dysprosium and other rare earth materials are also introduced.
