The continuous development of laser technology has put forward higher requirements for the optical properties, laser-induced damage threshold, and mechanical properties of laser coatings. Laser coatings with low absorption loss have very important applications in the fields of high-power laser and precision measurement. In this paper, the research progress of laser coatings in absorption loss control is reviewed from two aspects, including the deposition processes of E-beam evaporation and ion beam sputtering and coating materials. The absorption loss control methods in different manufacture processes during deposition, as well as the absorption mechanism and control methods of pure material and mixture material coating are introduced in detail.
