A significant limitation to the operating fluence (or peak power) of high-peak-power lasers is the laser induced damage threshold (LIDT) of optical components and optical coatings. A lot of work has been done to improve the LIDT of optical coatings in the past years, and recently, it is discovered that laser conditioning is a new technology to enhance laser resistance of the optical coatings. In this paper the latest experimental result from this group of laser conditioning of optical coatings at 532 nm is reported. The method utilized is the small laser spot scanning and the step by step energy raising. Coating samples, which were prepared with various deposition techniques, were conditioned. The effect of enhance of the laser resistance was shown in the great majority of the samples. The feasibility and effectiveness of the laser conditioning were confirmed. The possible mechanism of the laser conditioning was explained.
