If anyone feels like a gamble...

If theyre suggesting a pointer like pen that is qswitched and does picosecond pulses that are strong enough to destroy subdermal tattoo pigments powered by any type of commonly available battery then i say that is complete bs. U could maybe get 10-20 pulses from a fully charged 18650 before...

While i will agree that shining a light thru a phosphor should disrupt the lightwave coherence, i have seen i think on surplus shed and also on ebay lenses and just plain yellow crystals that were advertised specifically as being used to change the color of a laser from red to green or vice...

Be weary of unnatural generosity, if it sounds too good.....well yall know the rest. That being said however, the path of me becoming interested in lasers began after seeing a bunch of projects on instructables and then coming across someone on craigslist giving away a box with around 5 dozen...

Uhh i just saw like 2 days ago they were advertising 564 nm lasers on ali optlasers store. I would already have bought one but ive never ordered anything from ali before and i recall last time these were around some people received their orders and some people didn't and were getting the run...

Those are some great shots. Sounds like its been a really awesome opportunity/experience that you learned a lot from. Look forward to seeing some more of your work.

Nda4116 i dont have the money but i know these diodes are sought after so i figured id give everyone a heads up in case anyone is looking for one https://www.ebay.com/itm/Nichia-100mw-473nm-Aquamarine-Laser-Diode-NDA4116-/184130739239?nav=SEARCH

This makes me wonder what the physical properties of a light "object" would be like? Could you hold it? Solid? Liquid? Wierd science theyre cookin up these days...

Yah if you wanna do it the hard way u can use one of those units but if your covered head to toe in tattoos you no longer want and dont have the time to spend waiting hours while someone slowly zaps away at your skin... Then u gotta man up and go with one of these

With that tiny hole we punch nd then with the light that shines thru it might just be enough to grab the attention of our neighbor universes ancient scourge cthulu to come investigate the hole and worm his tentacles thru that tiny hole onto our plane to spread his beastial benevolence with...

I thought this was a decent article that did a good job at explaining (without excessive jargon/techspeak so that anyone can grasp) high power pulse generation and plasma mirrors https://arstechnica.com/science/2019/09/trampoline-mirror-may-push-laser-pulse-through-fabric-of-the-universe/.

Ya i was just referring to the NATO standard round. The first link that came up kinda referred to the ar15 and m4 loosely and interchangeably. And I realize the pressure will vary between rifles and barrels and there's a million different things that influence the pressure and velocity. I just...

Cool looks entertaining

https://www.unipress.waw.pl/wtlab/index.php?file=kop1.php Ok ill admit to the obscenely clickbait-eyness of the title but i couldn't help myself and I know that people are gonna see the thread title and instantly their bullsh#t alarm goes to defcon 10x ready to tear into this fool claiming to...

I'm usually kinda snobby when it comes to laser shows and displays. I mean it's all cool eyecandy and all, but scanning and tunnelling effects get kinda stale after awhile and ilda animations are often kinda cheesy and uninspired when it comes to artistic/creative reach. This installation...

A laser sight for a rifle? Or for like a rangefinder or measurement equip? If it is for a rifle mount it must be a fairly tough sturdy tube . Id suspect that the mirrors would frequently be thrown off alignment from the recoil? But then again its pretty old and stuff back then was usually...

I would say shine it thru the top thru the water (wear eye protection) Even if its only a watt or 2 its going to heat up a small spot of glass much quicker than the rest of the surrounding glass with liquid cooling one side of the glass. It might not crack normally but water is about 8...

Thanks for the infofrom you and everyone else that chimed in. I look forward to seeing if more of these pop up after new years. Nice build btw what is your driver set to/how much output are you getting do you know?

So uhm where are all these 495 diodes coming from? Is someone here linked with a sharp distributor? Does someone have credetials or a job that qualify to get engineering samples or development packs? Ive found that german site lasertack to sell them for too much money and its really irritating...

Cool pics im gonna dig thru my rock crystal collection and see what kinda cool effects i can get out of em. Glad to see your build was a sucess compared to your last one, keep up the good work!
