Because the photons of coherent light arrive at the target at the
same
time, they "pound" harder against the surface upon which they
impinge
than they would if they arrived at varying times. I imagine the
physics to be similar to sonic resonance. So perhaps the photons
don't have more energy, but they have a greater effect than light
that is not coherent.

I am afraid your concept of what constitutes a coherent source of
light is completely wrong. Why don't you read up something on the
topic?

This guys misunderstanding of basic physics aside, the topic was,
originally, the effect on pilots of exposure to visible light
lasers. It's
sort of on-topic for Sci.physics.

Sorry, none of that ever appeared on my computer.

I have many years of experience scanning
people with visible light lasers (Laser Shows) and it's my opinion
that the
claims are hype. Claims of retina damage are almost certainly
complete
crap. The current news involves a guy with a 5Mw hand held YAG
shining it
at a small jet and a police helicopter.

Whilst I think that would only be marginally dangerous, it was a
rather stupid thing to do.
I presume your laser shows are run with widened laser neams.
Do you, at the same time make very loud music which would result in
members of your audience being plagued by tinnitus?
