For the past several years I have been a guest at DARPA and had the opportunity to develop a Laser Assusted Particle Accelerator. It is a prototype for the Department of Defense and will most likely be deployed in some form on Navy vessels. The details regarding development are of course classified and I will probably delete this post in a few days. If it remains, you will know that they locked me up. I just hope you guys will visit.

As you would imagine it is not wise to get close to one of these during operation, so I put together a digital, radio receiver and transmitter operating in the UHF region which I can operate under my Amateur Radio liscense. W1RNY. I have tested it and with no obstructions can I be a quarter of a mile away. I am sure I can get even more distance, but I did not test it.

Here is the prototype in operation.
LAPA Prototype

Below are pictures of the initiator. It is digital which prevents activation by stray radio signals.

Please Note: No animals were used during testing but a tree brwas seriously injured and had to be euthanized.

The hardest part was getting the Particle source, and microton....which is a nano cyclotron into the empty shell of 3x Sanwu.

The transmitter receiver can be used with any laser though. You don't have to have a LAPA to use it...any laser. You just have to reconvigure the switch. The receiver has a relay that acts as the switch.

Not a bad thought, a good one in fact to post the LAPAdoodle device link lol

There are several real world efforts underway of a similar nature--have a look ---progress is progress.

For the fun of it, this site has a lot of laser beam reality information--is actually an information site not just Sci-Fi see: http://panoptesv.com/SciFi/LaserDeathRay/DeathRay.html

A lot of this I keep up with. My grandfather, Hugo Gernback, and Tesla were friends. Both of them came up with the concept of Death Rays at the same time. Gernsbsck described RADAR around 1911. My step daughter lives across the street from DARPA.

That's pretty cool. Hugo Gernback?

I had wanted to make a radio controlled battery box for launching model rockets but haven't done it yet, that and make some strong rocket motors with a different oxidizer but I've lost interest lately, what was in your tree branch that made all that smoke ?
I can see what looks like a 405nm beam in the cloud in your video.

That is what happens when laser excited particles hit a target. Tiny spot vaporizes and the expansion of gas causes smoke and bang.

Ok, so, I fibbed. I thought you were kidding, that surely you would know. I mix up some flash powder...sometime I add a little black powder, wrap it in black magicians flash paper (available from the magic warehouse in Baltimore) then wrap in clear tape. I actually vented this one by sticking a knife in it otherwise it would have been much louder!

Can you buy fireworks in your State ?
Unless you live outside any metro or suburban area where there's no zoning restrictions you have to limit anything you make to consumer fireworks limits, ( 1.4g ) use anything you make the same day, never transport or sell a self made firework.
I assume you know this but it's worth saying for anyone reading.

Absolutely! My wife and I were in TN a few years ago and I stocked up on some goodies. PA also sells them but I never purchased them there. We are out of the city limits in a suburban area which is right next to rural areas. One still has to be careful. Just like fresh pizza, you eat it the same day! Some time we have to talk on the phone about a friend of mine, bored retired millionaire and his blasters liscense and a place we had to open a camp out west to teach recreational blasting. Seriously lol.
