Thanks for the info ill check those patents out. Im inexperienced with gas lasers its all soo complex it can be hard to wrap the mind around this stuff. Whitelight/RGB sources have come a long way in a short time, i was marveling over this awhile back...

Like others have said it was probably one of those lab discoveries that simply couldnt be developed into a production level of reliability. I have no doubt that he managed to pull it off. But getting something to work in a lab full of millions of dollars worth of cutting edge hardware and...

Soo anyone wanna explain to me the functions of optical parametric generating/amplifying.? What purpose does the delay serve, is it for syncing the wavefront, making sure they're all polarized on the same axis? I'm not really that familiar with solid states and I've never even heard of a rgb...

This took my breath away for a moment. One beam goes in.....two are thrown out to their deaths... and three others go out and stroll off into the sunset??....

There are portable ground and truck mounted anti mortar laser units that have been deployed and used on the ground with jsoc spec operation teams in Syria and afganistan. Depending on how well they perform to provide cover from incoming fire in real world use, they could potentially become a...

Shame I'm up north in Washington I'd lov eww yo check out the lasers and artwork. You ever sell any of the holograms or copies of ones you produced? I'm certain it wouldnt be too hard to sell some of em thru an ebay or etsy's store?

I have a red one I pulled from some broken gadget that looks like that with the exception of the trim pot. It was mated to a low power 5-20 mw red either 650 or 638nm.

Interesting thanks for the info. I wasnt aware you could make them out of photos.

That plant hologram is beautiful. I'm surprised it captured that much detail. Is there a special technique that helps when trying to get a holo of an object that has really complex structures like a planr spread over a wide area, I've noticed most holograms I come across are of small objects...

How much was it. Never bought anything off Alibaba but I remember seeing those listed for dirt cheap but never bothered after reading folks bought some of the 575nm but a few never had them shipped and sounded like they were getting the run around

The bar in front if the diode sounds like it's for steering the headlights in the direction your turning as some newer cars do this. Either that or some cars now automatically divert the light from traffic that's oncoming so not blast drivers in the oncoming lane with ur super laser hi beam. Can...

Ebay has em for like 20 bucks I've seen. I wanna say techood but I could be mistaken. They're yellow not transparent but if I remember correct there was the option for a reflective phosphor or a transmissible one. Looked kinda plastic and cheap more suited for a flashlight but anyway ya I'm sure...

All of the above i answered. I agree with others that posted i believe that theres aliens but i doubt they would invest the incredible amounts of time effort energy and resources to come to our planet just to play peekaboo. My theory is what we typically refer to as aliens are either our own...

Oh ya i forgot abouth meredith. I dunno what your budget allows but if ur able to drop a few bills you can get a decent hene and powersupply from here https://www.mi-lasers.com/

Not sure if itll help but if ur going for cheap find a used laserdisc player thats in working condition the older models often have tiny hene tubes inside u can salvage?
