The invention discloses a double-beam synchronous following anti-reflection device for laser forging printing, which is characterized in that the specific wavelength combination of 1064nm powder bed cladding laser and 532nm green ultrafast strengthening laser is adopted to impact a fusion layer, and a special reflecting coating with the wavelength of 532nm is coated on a scanning galvanometer mechanism; therefore, the coating can selectively transmit laser of 1064nm and efficiently reflect laser of 532nm at the same time by utilizing the obvious wavelength difference between the two; on the basis, diffuse reflection of green ultrafast laser can be selectively isolated, so that damage to the laser caused by return light is fundamentally avoided, stable work of equipment in a long-time and high-power following mode is ensured, and therefore, the device is very suitable for large-scale application and popularization in the technical field of laser forging printing.
