Actually, yes there is a laser detector available and the device is
simpler and cheeper than a radar detector! Cincinnati Microwave sells
one for only $99 and it works very well ( from what I have heard I do
not own one ). I believe the laser beam is used as more of a scanning
beam than a single beam so it is fairly detectable. It would be very
hard for a police officer to point a single laser beam at a car moving at
a high rate of speed. I would expect that also since the light within a
laser beam is coherent it would be very easy to determine it is present
even when it has bounced off of things like the automosphere...
