The laser energy covering the defect in laser-conditioning process is studied, and its characteristics in different laser-conditioning processes are analyzed. Theoretical analysis shows that, with the same conditioning efficiency, the laser energy coverage rate of single-step conditioning is better than that of multi-step conditioning. From laser-conditioning experiments of the HfO2/SiO2 high reflective coating deposited by E-beam evaporation, we know that the LIDT (laser-induced damage threshold) enhancement of the coating after single-step conditioning is better than that of the coating after multi-step conditioning with the same conditioning efficiency. Using the highest irradiating energy of 112% E0, the LIDT of coating after 5-step conditioning is 183.5% of that before conditioning.
