Abstract :
The paper bring forward a design of multilayer structure which has a high reflectivity for 1.82μm laser beam and a high absorptivity for 1.48μm laser beam. The experiment reveal that the absorptivity of the film reach to 95% at incidence angle from 0° to 40° for 1.48μm laser beam and has a high reflectivity for 1.82μm high power laser at incidence angle of 30° at laser power density above 500w/cm2.
