That's only true if those beams are lasers/composed of photons. We don't know that, and there is even strong evidence against it (the fact you can see the contributing beams in the DS superlaser, for example).
The weapons employed by the gunships and their relatives interest me, although not for any supposed soliton properties. Either they have very low yield (yet damaged a spaceship in AOTC) or they demonstrate an interesting sort of confinement that is preventing whatever's in the beam dumping much energy into the atmosphere.
Was there a question here, I throught that that I believe the fact that we see the interaction of several Beam an example of soliton wave combining to form a single Soliton. And would not the fact that the energy of the laser being lock into self focusing packet explain the apparent looking low yield but yet having the power to punch thru the defenses of the Federation Trade ship.. If it a single Soliton, that is, but that my take on the scene...

If that the case then Creation of self focusing packet of EM energy is also possible, and it no small step to create an packet that can decay and explode like a light bullet.

I thought your post about focussing talked about requiring a plasma. Alternatively, the Empire is building weapons based on a very small effect (photon-photon interaction) that would only affect a tiny proportion of the energy in the beam. Doesn't it seem strange to you that anyone would build a weapon based on such tiny effects?
Yes a plasma would be one way, another would way that I was concertating on was a direct Photon to photon interact. Why well let me qoute the following article from Phys. Rev. Lett. 87, 171801
(issue of 22 October 2001 Title teaching photon to trangle
"To overcome the low probability of photon-photon scattering, a group of theorists at two Swedish universities has proposed trapping lots of photons inside a so-called resonant cavity. This cavity concentrates photons of particular energies (modes), much like an organ pipe concentrates acoustic energy of certain frequencies. By pumping a lot of photons into just the right modes, photons of two different energies could smash into each other, exchange some of their energy, and then fly off with two new energies that were not among the original modes. The detection of these new photon energies would indicate the existence of photon-photon scattering, according to team member Mattias Marklund of the Chalmers University of Technology in Göteborg.
"It's a nice proposal," says Mordechai Segev of Princeton University, who has proposed searching for photon-photon scattering with high power lasers. He says that such scattering--if it could be observed--would be the first example of so-called nonlinear optics in vacuum, a class of optical effects that don't normally occur without high power lasers and a material medium. Another example of such effects is self-focusing, where the lig ht confines itself into a beam that doesn't diverge. If this can be done in a vacuum instead of matter, says Segev, it might lend itself to some far-out applications. Assuming future lasers can be cranked up to the level where self-focusing occurs in a vacuum, then the beam could propagate over huge distances--maybe even from our galaxy to the one next door--without dissipating. Closer to home, the nonlinear effects might be used to create new laser frequencies at very high power, something laser physicists would be delighted to do.
Marklund hopes to try out their proposal using high power microwave cavities like ones currently used to boost beam power in particle accelerators. These can store huge quantities of photons, and they might reach the power needed for photon scattering, he says. The Swedish group is talking with Rutherford Laboratory in the UK about setting up resonant cavities to search for photon scattering in a couple of years.

A payoff a long range Laser , a tunable laser. Two good one.

[...blazars]
--------------------------------------------------------------------------------
Assuming this hypothesis is correct, and the deviant spectrum of blazars is due to photon-photon interactions, your own quote says that the cross-section is maximised when the interacting photons have very different energies. Are you claiming that TLs are both lasers and (very) polychromatic, or are you saying that an already miniscule effect is reduced to even lower significance by the use of monochromatic photons?

I figured you were playing devil's advocate in your previous few responses to me.

Unless the "flak-like manner" is actually caused by a shield or forcefield interaction with the target, and they can't fire full-power shots at very long range because they're space fighters, they perform like shit in atmosphere, and they have trouble accurately tracking a moving target with fixed-axis guns at long range. So they would be fried by the shockwave and fireball from their own guns at full power, and it makes more sense to get close and fire low-power shots to harass and damage the Falcon.
--------------------------------------------------------------------------------
Some targets with flak around them are supposed to be shieldess (airspeeders at Hoth); more power typically means longer range with SW energy weaponry, including atmospheric weapons; granted; TIE guns can fire off-axis, so accuracy in that regard shouldn't be too bad.
I think you misinterpreted what I mean, though. I wasn't saying it'd make sense to fire at long range, I was saying it would make more sense to set the flakbursts to appear at long range (or not at all, if possible), while firing at short range. That way, hits to the shields would cause them to absorb full power shots, while misses wouldn't cause a flakburst that'd kill the TIEs.
So if there are flakbursts, it is very likely that the flakbursts do not release the entirety of the beam's energy.

If most of the beam continues on indefinitely and invisibly, one would think that we would have seen one of these beams damage something at some point in one of these battles.
--------------------------------------------------------------------------------
In that case, one would also think misses that don't explode but visibly continue on would also eventually hit something. Most of the battles with the mid-air explosions being seen takes place in environments where there is not much to hit, so it'd be rather tough to see any effects from the rest of the beam.
I didnot see that this was exactly how it was done, just that the effect is observable in nature, maybe some SW scientist attempted this approach, just like earily experimenter in flight try making fly machine that mimic bird flapping motion in aircraft. This lead to some truthly funny films, but also show them how not to do it.

--------------------------------------------------------------------------------
You've ignored my counter-arguments, then. No, it wouldn't be the logical conclusion. In nature, we're all held to the ground by a nice big gravitational field - must it therefore be inevitable that starships of the future will have gravitational weapons? After all, gravity occurs naturally, doesn't it.

Look at Antigravity that SW uses, very effective low power consumation. While present research show that such effect if it exist, would be very tiny ( 1% different in weight of the object compare to it normal weight) and requires superconductor and hi power.
--------------------------------------------------------------------------------
I'm not commenting on the antigravity research, and do not know if it really is antigravity or an electromagnetic effect, because I haven't followed it extensively. Fair's fair, you haven't answered on my counter-arguments, either.

Does that that means we say well if such effect exist it tiny so that Antigravity is not used in SW and say that EU and rationalize what we see in the movie as magnetic levitation.
--------------------------------------------------------------------------------
Ah, you catch me at a weak spot. I'll merely reiterate that in my opinion, gravity is usually the first casualty of science fiction.

You don't know what I think about this idea.
True and that and the all no noise in space thing..By the way I would like to hear you opinion on this, maybe we can start a Post in Pure SW someday.
.
I have no strong conviction on flakbursts or shield/bolt interaction. I do have a strong conviction that you're talking rubbish. I've already answered this argument with some counter-arguments and you've ignored them.
Okay I answer your counter agruement and maybe my agruement are rubbish, no more than anyone elses at time, but at least I try to post some Valid point and seek answers to some of the question faceing us with the varies SW technologies.

and Optical physicist are experimenting with Relavititic Plasma to Create self focusing effects.
--------------------------------------------------------------------------------
That's been discussed and it's been pointed out why it doesn't match TL behaviour. You've just decided that optical solitons are involved, and evidence be damned.
Has it ? and you can read my mind on What I decided, funny I am not sure really if Optical Soliton are really involve. It could be some other exotic Energy that travels at C, Saxon never said it was "Electromagnetic", Just that it travel at C and that the main potion of it was invisible. Since Tibanna Gas is involve it could be some form of Hypermatter/ Energy who properties lend it to soliton like solution. All I wanted to point out that a missile/projectile need not be involved in creating the Flak.
