All very interesting.
Perhaps I'm being paranoid but what concerns me is the concept of a 'false alarm'. It sounds innocuous enough but the firing system has to be entirely automated for obvious reasons. There will be no human intervention or moderation. If 'false alarm' means that the laser is fired at an aircraft instead of a missile, that is a serious matter.
Is this equipment going to be more reliable than any other electronic gear in an aircraft? Most safety-critical equipment is extremely reliable and has very low levels of failure or false alarm, but yet is still duplicated or triplicated. Yet here we have an equipment that if it fails could potentially be a threat to any other aircraft which it overflies, with no backup or crosscheck from another instrument.
Divide the MTBFF (mean time between false firing!) by the thousands of aircraft that will be flying with it, and the danger of an accident seems very real.
Perhaps we should all be wearing IR-filtered goggles?
