Hi:

Is it theoretically-possible to facilitate hydrogen-hydrogen fusion
within the earth's troposphere using a laser? If so, what would be the
maximum wavelength [or minimum frequency] and minimum intensity of
laser light required for this? Also what would be the minimum
thickness of the laser beam necessary for this application?

The application of this nuclear fusion is not generation of power but
rather to produce a spectacular light show in the night sky -- using
the minimum light intensity, maximum wavelength, and minimum beam
thickness required.

I am guessing that the minimum wavelength required is too short for
the human eye to see. However, the effects of the laser-induced fusion
maybe visible.


Thanks,

Radium

Sure, all you need to do is build your lasers from unobtainium so they
don't vaporize when you turn them on and power them with a couple
of Galaxy class starship matter-antimatter reactors.

Or, you could use ordinary lasers directly like the laser light show
people do.

Oh, don't forget to notify the FAA you are going to do it or you go
to jail.

Please don't joke. I am asking a serious question.

But the fusion-induced light will be much brighter and will cause a
lot more EMI/RFI. Right?

Okay but what if this laser is on a football field and pointed upward
during the show?

Not even likely.

The answer is always "no, and you are stupid for asking."

No, you aren't. You are simply asking the latest in a series of
increasingly-stupid questions that betray the fact you have no
education in physics.

If you were serious, you would have learned something about laser or
fusion physics by now. Except you haven't, which means you are either
stupid or not serious.

Right, and violate a whole bunch of laws.

Shining a laser into the sky without notification is illegal, period.

If it is over a football field, why the hell would you want it in the
troposphere?

You forgot the other alternative; mentally challenged, or as we used
to say, that boy ain't right.

No. Are you a troll or did you not bother hitting wikipedia for
nuclear fusion.

Almost all hydrogen on earth is protium, with some small percentage
being deuterium... so you're trying to do p-p fusion which is weak
force mediated... you have to overcome columb repulsion at the exact
same time there is a weak mediated inverse beta decay to a neutron,
positron, and electron neutrino. Thats how the sun shines, and the
reason its so slow and hard to do is the reason its still shining
rather than burning up billions of years ago.

This ignores a little problem with nuclear fusion called confinement
or the Lawson criterion.

http://en.wikipedia.org/wiki/Lawson_criterion

The application of this nuclear fusion is not generation of power but
rather to produce a spectacular light show in the night sky -- using
the minimum light intensity, maximum wavelength, and minimum beam
thickness required.

Better luck just building H-bombs, deuterium-deuterium wet Ivy Mike
things or deuterium/tritium for something you can launch on a plane.

I've been wondering alot lately about fusion and probability. Coming from
the perspective of my own very strange views on physics, I think that there
may be a possibility of approaching the question of fusion as if it were
actually a question of probabilities somehow.

Unfortunately I dont really have a mathematical model of the atom to work
with, just a philosophical one. So, all I can do is tell silly stories and
spew bull****.
