MERGING LASER BEAMS INTO ONE BEAM (WHERE HAVE I HEARD THAT BEFORE?)

I received the following article this week from Mr. J.K., and when I read it, I had to smile... very nervously, for it seems that scientists have figured out how to combine several laser beams into one beam, to increase the power of the emergent beam, and also to reduce the heat generated from just one large, rather than several small, beams. That, of course, is the premise of George Lucas' rather fanciful one-shot planet-destroying weapon from his Star Wars movies, the Death Star. But, believe it or not, that's not what made me smile nervously, for obviously, humanity is nowhere near being able to construct an object that big to house and aim an equally gigantic laser, much less to move it through space.  What made me smile nervously was...

... well, read it for yourself:

It’s Now Possible To Combine Lasers Like In The Death Star

Just for kicks, we can add the following much more scientific article, before returning to the first:

Photonic Frontiers: beam combining - Combining beams can boost total power

Note, that in the second article, it is admitted that combining several beams into one can be a method of dealing with the problem of the tremendous heat that lasers generate, and also that it is a method for increasing power, with this very important caveat:

Combination of larger arrays of laser elements to produce good quality beams has been demonstrated only at lower powers. Other challenges include balancing the tradeoffs between diode arrays and arrays of fiber lasers, reducing the light lost to side lobes, and efficiently combining light from input arrays with relatively low fill factors.

The big questions are how high can the power go, and how well will it scale?

Our friends at phys.org are a little more "flashy" in their coverage of the phenomenon:

The Star Wars 'superlaser' may no longer be sci-fi

Diamond makes laser beams more brilliant

Basically, the new technique involves shooting several laser beams at a very pure diamond, which due to its lattice properties combines the incoming beams into one outgoing beam, and at the same time changing its frequency. The result is an increase of power in the beam, without the increase of heat that would be generated by one beam to begin with.  Then comes this admission from the first phys.org article cited above:

Although other materials have exhibited the same type of beam combining properties, the choice of diamond is essential for high power. The power-transfer effect at the heart of the device, called Raman scattering, is particularly strong in diamond. Also, crucially, diamond is outstanding for its ability to rapidly dissipate waste heat.
At this point, my calm smile, brought on by confident knowledge that we were nowhere close to being able to build gigantic moons with laser beam-combining to blow up planets(much less actually be able to move the thing), began to acquire a slight twinge of nervousness, for the final statement indicated that "they" were testing the whole technique on a variety of materials, doubtless to find the most optimal for power output and heat dissipation.
Which brings us back to the first article that Mr. J.K. sent me, where, sure enough, my worst suspicions were confirmed:

Planetary destruction is not on the cards for this technology, but it has applications for both defense purposes and scientific analysis. Laser technology is crucial in many areas and this will allow lasers to go beyond the current power limits.

“Researchers are developing high power lasers to combat threats to security from the increased proliferation of low-cost drones and missile technology,” Professor Mildren explained. “High power lasers are also needed in space applications including powering space vehicles and tackling the growing space junk problem that threatens satellites.” (Emphasis added)

And of course, what can be used to zap "space junk" into vapor can be used to zap satellites, or missiles, into vapor... and one day, perhaps, on a sufficiently large orbital platform, to be used in more horrific offensive strategic "mission configurations" against ground targets...

Smile. Remember, we're nowhere close. Remember, that when H.G. Wells started writing about atomic bombs in his science fiction at the turn of the last century, it took a whole 45 years to invent them. Have a nice day.

See you on the flip side...

  1. This kind of gives a new twist to all that research on developing artificial diamonds…

    Also, I couldn’t help but think about that dis-aster when the scientists initiated a laser beam onto the pressurized diamond-anvil that they had just (allegedly) produced metallic hydrogen within. The diamond-anvil went crunch and/or exploded. I wonder if the diamond was not pure enough, or whether hydrogen atoms had permeated the carbon lattice, weakening it? Or, if they used more than one laser, they had a beam-combining effect?

    It might also be worth looking further into the old cuneiform tablets as to whether diamond was a material praised or cursed by Ninurta, after his taking the Great Pyramid…

  2. Kooky woo woo coincidence, clairvoyant illiterate Grandma (who was born in an Eastern European village and doesn’t even know what Scifi is and doesn’t watch TV) had a dream of men looking for people hiding underground and killing them with lights (lasers) from the sky.

    What can be pointed up to destroy ‘space junk’ can just as easily be pointed down.

    1. Where’s the Ka-boom.. There was supposed to be an Earth shattering Ka-boom.. love it.

      We need Bugs Bunny to save us now.

      Bring back big Eared Messiahs.. and I’m not talking about Royalty..

  3. Perhaps this ransacking of the Middle East is in search of the Giza capstone diamond? But what is the Deep State going to do when they find it? Ivanka Trump will want it for her own collection. Possibly Goldman Sachs has determined this likely outcome and that is why they are concentrating on mining asteroids—- they plan to find a diamond big enough for the Giza machine that they can then sell to the Breakaway Nazi Civilization who desperately want to turn the Giza weapon back on and convert Earth back into a death star and end its sad sojourn as a colony for lost souls. Its part of the nazi’s Make Earth Great Again campaign or MEGA.

  4. Last week.. In a country not too far away from where you’re seating right now….

    Episode 55 : Deep State gets away with it again.

    The Evil Deep State has been dampening any latent Jedi powers on Earth for the last 57 years from developping through harmonic disscordance.
    Darth Soros and his apprentice Darth Hillary have been beaten by an Orangu-Trump and their recent grasp at global hegemony has been thwarted.. Or has it.. Realising that they’d soon need a scapegoat due to Grand Moff Skippy Podesta not knowing that you need a more complicated password than ‘Password’ to protect your emails.. Hillary followed the rule of One and was sacrificied in order to make way for DarkTrump and his Hairpiece of Terror..
    The Rebel Alliance thought that they’d been exposed through their vile underbelly of human trafficking and child abuse and murderous rituals, but unfortunately the corruption went too high.. Higher even than the visible gouvernment put on for show to amuse and confuse (and terrify) the masses.
    In order to punish the insolent masses for their cheek, they’ve decided to burn them all under a big magnifying glass like the little insects that they are..

  5. Makes you stop and ponder whether Lucas had access to unknown knowledge regarding advanced tech and those Kyber crystals.

    1. Trust me sagat1 George Lucas had access to such knowledge. Lasers can also be used to propel spaceships throughout through out the solar system and beyond. That’s the problem our overlords are always obsessing on new ways to commit industrial murder known as genocide.
