Using lasers to make... Voices?

originally posted by: RadioRobert

Imagine being in a squad of dissidents approaching an enemy installation at night and all of a sudden there is an explosion of sound of light and it sounds like a machine gun firing right next to you. Then after you've all hit the deck you notice a bouncing blue ball come over and say, "hi". Literally giving you instructions on how to disperse if you want to live. Squad leader gets his # together, says ignore the light, it's just a trick. The ball heads over and starts crackling as it burns small holes in the squad leader's clothes until he starts screaming and running. At which point everyone has had enough and decides to head for the hills. The blue light chases you for a bit and says, " have a nice day".

This is SciFi stuff.

Similarities abound.

No telling whether the story is true however the behavioural responses seem fairly realistic - i.e once you have the dematerialising plasma ball that chases people around with an almost magnetic attraction - you probably dont need any other bells or whistles.

Curious, isn't it?

did you know that they first got this stuff to work in the early 80s. by late 80s to early 90s were deploying it. did you know that what you're reading about in this thread and associated links provided is just the tip of the iceberg for this sort of technology and it's myriad applications.

It would make sense as people have been working on directed energy systems since at least the 20's.

Careful with the 'ole sweeping, grandiose statements of fact with zero citations though...

I don't need citations to prove this to anyone. just trying to help you guys along on this. take it or leave it makes no difference to the reality.

When a disembodied plasma ball asks you if you are a god, Ray,...

I found (stumbled across, again) the technical name of non-spreading guided beams: Bessel beams.

Here is the phys.org article where they use air beam in an array to guide and turn smoke (as a demo) in mid air and they mention Bessel beams: Scientists accelerate airflow in mid-air.

A quick googles will show femtosecond lasers making vortices. 2016, High-power, diffraction-free femtosecond vortex for laser materials processing.

Back in 2012, these other guys used two Bessel beams to make a "tractor beam".

Things like that always remind me of the attributed Ben Rich quote, "Anything you can imagine, we've done."
