No offense but if you don't have anything pertinent to say, then please
pound sand where the sun doesn't shine.

I asked an interesting question. Please answer it or I'll keep posting
it. I hate it when my interesting questions are not answered properly.

Is it physically-possible to design and build a 400 nm laser that is
directly-"pumped" by aneutronic nuclear fusion and in which the active
laser medium is a rare-earth crystal? If not, then why? Why isn't it
possible?

The "pump" is the part of the laser that excites the atoms in the laser
medium.

Hydrogen-Boron fusion is an example of aneutronic fusion. 400 nm is the
wavelength of "black light" and is about the shortest the human eye can
detect. 400 nm is the longest wavelength considered "black light" and
causes fluorescent substances to glow.

In aneutronic fusion no more than 1% of the total energy released is
carried by neutrons.

No offense but please respond with reasonable answers & keep out the
jokes, off-topic nonsense, taunts, insults, and trivializations. I am
really interested in this.

What do you want to use it for?

Well, I dream of using this for a variety of applicationa.
Telecommunications and power supply are two signficant purposes.

One potential advantage I see, is that -- unlike electrical devices --
these optical devices will not be damaged by solar flares [a common
cause of blackouts] or EMP [ElectroMagnetic Pulse].

So using light -- instead of electricity -- as a power source has this
benefit.

In this hypothetical situation, the following would likely be utilized:

The power supply starts off as a high-power 400 nm laser that is pumped
by aneutronic fusion at a remote power station. As the laser light runs
to my home, it does not do so at full-blast -- that would mean total
destruction in everything in the path of the laser. Instead this
gigalaser is used to power and pump smaller less intense 400 nm lasers
which lead to my house. The lasers get smaller and less intense on their
way from the power-station to my house. At my house they provide the
same amount of power that a normal electric socket would provide.

Telephones and cable television would also benefit heavily from using
the coherent light in place of electric signals. Optical signals can
carry far more bandwidth than electric signals.

Now how does one convert 400 nm laser light into motive power? Well,
there are certain proteins that change shape when exposed to light.
Perhaps contractile proteins -- similar to those found in our muscles --
could be constructed in such a way that they would contract and relax in
a manner analogous to the intensity of the blue light they are exposed
to. Muscle cells from donors could be bioengineered so that they respond
solely to 400 nm light by changing their contractile state.

Also, I would like to use this laser light for cybernetics -- i.e.
connecting the brain to optical digital computers. Certain types of
proteins at certain concentrations can be made to code for 400 nm laser
light of varying intensities and rates; and visa versa. The rate at
which the intensity of the laser light varies could code for various
concentrations of certain protein. Many neurotransmitters are proteins.

The neurons in our retinae, respond to light as they have photoreceptors
attached to them. When photons hit a photoreceptor, there is a
photochemical reaction involving proteins. Some bioengineering could be
done on the brain so that the brain's neurons also sprout photoreceptors
that specifically respond to 400 nm light.

The reason I want aneutronic fusion is that it is more solid state than
other types of fusion. For example, deuterium-tritium relies on emitting
neutrons to hit and boil water making the steam move a turbine. I want
solid-state power which is why aneutronic fusion is the best bet.
Aneutronic fusion can directly generate photons and pump a crystal,
where as D-T fusion would require a lot more steps to get the intended
result.

What do you think is carried on all those fiberoptic lines
all the telecommunications companies put in over the
last decade or so?

The problem is they still need electricity for power to generate the
optical signals. Why not go one step further and make the power source
itself optical? That way, less conversions will be necessary, and the
devices we take for granted will still function as desired even during
the nastiest solar storm or EMP. No more worrying about equipment damage
from lightning either.

The world is consistant, you are still an idiot.

You and habshi should be locked in the same ward where you could
babble nonsense to each other endlessly without distrubing the
sane people.

And how to you propose to get hydrogen and boron to fuse without
consuming any electric power? Put them next to each other in a beaker?
Pesky details!

Your scheme is a little like (except a little Further Out There) those
who foam at the mouth about the virtues of hydrogen power. ... of
course, first you have to find a cheap source of hydrogen ...
"Water! Lots of hydrogen in sea water!" Of course, you need a boatload
of power to electrolyze water.
"The sun then! Lots of hydrogen in the sun!" Of course, you need a
boatload of fuel to get the tanker up there to fetch it.

And just how do you propose doing that? The best photovoltaics still have
abysmal efficiency.

It's a dream thats unfortunately unlikely to happen in my lifetime. The
main problem is that igniting aneutronic fusion requires SO much energy.

Um, photovoltaics are also electric. I am thinking of not needing
electric power at all. Instead of using electricity, use 400 nm laser
light. So photovoltaics are totally out of the question.

I would like the 400 nm laser should be pumped by aneutronic fusion. The
lasing medium should be some kind of rare-earth crystal. The light
energy emitted from the aneutronic fusion should cause the atoms in the
rare-earth crystal to emit 400 nm light after exciting the electrons in
those atoms. When photons resulting from the fusion energy are released,
they hit the atoms in the rare-earth crystal. This causes electrons in
those atoms to initially move to a higher-energy state, then from the
higher-energy state back to the lower-energy state. When the electrons
move from higher-energy to lower-energy state in the crystal's atoms,
they cause those atoms to emit 400 nm light. The laser has two mirror,
one with specs of silver, the other without. The 400 nm photons will
leave the half-silvered mirror. The laser now emits 400 nm light.

No. Why do you think that would happen?

Come on, PD! You sure aren't much of a Liberal are you?

Don't you know that it makes no difference if your ideas actually WORK
or not, the important thing is that in the face of a problem that you
DO SOMETHING!

Sounds silly, doesn't it? But the same thing works for research scientists
and test pilots, so there has to be something to it.
