The idea of a space-based laser gun was disclosed in the journal Chinese Optics in December 2013 by three researchers, Gao Ming-hui, Zeng Yu-quang and Wang Zhi-hong. All work for the Changchun Institute for Optics, Fine Mechanics and Physics – the leading center for laser weapons technology.“In future wars, the development of ASAT [anti-satellite] weapons is very important,” they wrote. “Among those weapons, laser attack system enjoys significant advantages of fast response speed, robust counter-interference performance and a high target destruction rate, especially for a space-based ASAT system. So the space-based laser weapon system will be one of the major ASAT development projects.”The researchers propose building a 5-ton chemical laser that will be stationed in low-earth orbit as a combat platform capable of destroying satellites in orbit. Given funding by the Chinese military, which is in charge of China’s space program, the satellite-killing laser could be deployed by 2023.According to the article, an anti-satellite attack in space would employ a ground-based radar to identify a target satellite, a special camera to provide precision targeting and a deployable membrane telescope that would focus the laser beam on the target satellite.The article also reveals that in 2005, the Chinese conducted a test of a ground-based laser weapon that was used to “blind” an orbiting satellite.“In 2005, we have successfully conducted a satellite-blinding experiment using a 50-100 kilowatt capacity mounted laser gun in Xinjiang province,” the three researchers wrote. “The target was a low orbit satellite with a tilt distance of 600 kilometers. The diameter of the telescope firing the laser beam is 0.6 meters wide. The accuracy of [acquisition, tracking and pointing is less than 5 [microradians].”

Take his stuff with a few grains of salt. In the past he has had good sources and reasonable (not great) analysis. However, he is very ideologically-driven: he really dislikes the Chinese. The result is that to him, everything is a threat. If somebody gives him a Chinese fortune cookie he will interpret it as a sinister plot to attack America.
