Beschreibung
Zusammenfassung:	The invention discloses an infrared guidance laser absorption film which comprises a bottom layer metal thin layer and a surface layer medium thin layer. The two layers of structures of the absorption film are connected into a whole and are manufactured by using a coating technology. The bottom layer metal thin layer is made of nickel materials, and the surface layer medium thin layer is made of silicon or germanium materials. The surface dielectric thin layer is designed to be an optical Fabry-Perot (FP) resonant cavity. The bottom layer of the absorption film reflects incident infrared laser, FP resonance is formed in the surface layer, energy of the infrared laser is dissipated, and therefore infrared guidance laser is absorbed, and reflection of the infrared guidance laser is remarkably reduced. The method has the beneficial effects that wide-angle high absorption of infrared guidance laser is realized, and large-area preparation on a base material or a flexible substrate is facilitated. 本发明公开了一种红外制导激光吸收薄
