Background: I am a writer for the magazine Aviation Week and Space Technology, which is a trade press journal serving the aerospace industry.  We will be running a series of articles over the next several months about reducing the hazards of orbital debris (including, for example, satellites that are no longer controllable, old rocket parts, and shrapnel from accidental or intentional collisions).
Request: I need to find information about the plans of the Japanese firm JSAT to use space-based lasers to clean up orbital debris.  Information about the design of the technology, plans for its use, and business considerations such as market size and capital requirements are all of interest.  I am specifically interested in JSAT's plans involving orbital debris cleanup, so information about other uses of space-based lasers are not of interest.
