Advances in space laser coating for space exploration

Abstract

With the advancement of space laser technology，laser systems are progressing towards shorter wavelengths，longer lifetimes，and higher orbits. It requires higher performance coatings that can withstand the damage caused by the harsh space environment，such as vacuum，high and low temperatures，proton radiation and Gamma-ray radiation. This paper reviews the development direction of the main space lasers at home and abroad. It also discusses the effects of the space environment on coatings during the development of space laser systems and the evolution mechanism of coating performance under service conditions. It presents the new advances in high-performance space laser coatings and provides insights into future development directions，such as gravitational wave detection in space and deep space exploration.
