Which type of laser is best for nanotechnlogy?

[Pooh Bear]

Mumbo-jumbo, psuedo-science babbling word salad that sounds like
dialog from a sci-fi TV show canceled after two episodes.

SsssHhhhh ! Don't say that. it's getting good.

And FYI, hot pizza and cold beer is the essence of life though from
your posts I highly doubt you are old enough for beer.

MMmmmmmm. Pizzaaaaaaa !!! Bbeeeerrrr !

Digital brain interfaces are physically-possible. Its just that today's
technology isn't anywhere near making such devices.

Yes, but to stimulate more, you must have OTHER neon atoms.

Alright, fine... zero point FOUR nanometers. :^)

(Eh, mean free length between Ne's would be a good bit longer than that I'm
sure- but whatever.)

So re-read my question as "can you get a HeNe cavity shorter than 632 nm?"
I suspect the answer might be "No".

Hmm might have me there. Should be able to make a 1/2 wavelength cavity of
sorts though, no? I forget what the dimensions of a diode laser are, but I
remember it involves some wavelength-order thin layer of active material.

Let's fire a digital laser into your brain to see shall we ?

At what wavelengths, exactly?

This is going strangely, it makes me wonder if there could even be a laser
emission from parts that are smaller than that wavelength. I guess some
kind of emission might be possible, just as long radio waves can come from
short aerials, but I can't imagine what could make lasers work that way.
Surely only by synching parallel emitters, and that would be cheating.

As Sam just mentioned, emission from a single atom qualifies as laser
emission. Not very helpful, but that's another matter.

If only it were that simple

Then I guess you've never heard of neuroprosthetics.

But we'd be farther along if Wesley Crusher's nanites hadn't become
self aware and left the ship to form their own civilization...

Which is more practical, photonic neuroprothesis or electronic
neuroprosthesis?

Well, let's see...

All the "signals" within living organims are electrical and have
maximum frequencies in Hertz.

The main reason for using optics over copper is to achieve gigahertz
bandwidths.

Take a guess.

A classic example of using massive parallelism to acheive huge processing power
over clock speed.

bandwidths.

Indeed. Optical is overkill.

I can get 10m E-M waves out of a pocket sized walkie-talkie

Were you by any chance assuming I said you couldn't?

Where can I find more info on nano-scale lasers? Are nano-scale lasers
the smallest possible?

No, since the idiots in laser tech have a mental malfunction
concerning the words tech and scale.

They are like biologist, since they're mostly chemists,
and mostly morons.

lasers have no smallest scale, since they work on
energy pumps, not material science.
