and I honestly don't know the answer. I know that the Laser Clearinghouse (not to be confused with the Publisher's Clearinghouse) is concerned about accidental blinding of US space systems. I'm reasonably sure they're also interested in protecting the space systems of friendly nations. As for hostile nations, such as France, I really don't know. Intentionally blinding a satellite could be considered a hostile act (but what could the French do about it?).

Remember, you don't necessarily have to hit a satellite with a lot of energy to have an effect. If, for example, you "dazzled" the Earth sensor and caused it to lose Earth-lock, you could well cause the satellite to go into survival mode. In this mode, the satellite automatically shuts down almost everything except the heaters.

You may also be able to dazzle optical imagers even with low radiated power. This sounds like a good experiment to try on a SPOT satellite. I'm sure elsets are available. Who knows, the LCH might not only look the other way, they might get a laugh out of it.
