One of my first NDG7475 520nm. This started happening a while ago but I ignored it. Whenever I turn it sideways, it does this and the brightness drastically decreases. This is without any lens on top. Is this inside the diode or what?

I would like to build or acquire something that would reach and be seen from very far away. Similar to those concert lights: https://www.farralane.com/swisslas-pm-4000g-pure-diode.html I don't mind paying that price for it buuuuuut maybe I could build something more effective. A dozen...

So, I left my incomplete 1.5W 520nm build with my girlfriend and when I came back, she had done this with some electrical tape. She's in medical school and thought it would fit her better. Looks alright.

I just want people's opinion on what type of weapon this might be? This is above earth btw. What would you need to go out of the atmosphere like that? Definitely not a laser since it looks like a "missile" projectile type shot. Plasma? It starts at :15 seconds, upper left. The "projectile"...

Just wanted to let you all know that I'm changing my name to Vision. Just to clear any confusions.

So, after the demise of my new NUBM44 6W+ 445nm. I wanna get another one but after seeing the divergence, I don't know... I currently have: 3-4X 1W 445nm 1 x 2.4W 445nm 1 x 10-20mw 450nm 2 x 100mw 650nm 1 x 1W 520nm > Driver not working ATM. I have a 500mw 405nm somewhere. I love power...

I was using a flashlight driver for it and just got the X-drive, but its not turning on? Something wrong with my setup or something? I'm using the ehgemus host as contact points, so its not anything else.

Long story short, just built my laser, was outside trying it, started to rain, hide it as quick as I could but I'm guessing some water went in? Its really dim, its heating up real good but dim. $200 done or not? I had just received my Ehgemus host from Chrisbee and now I messed the diode...

My lens had some dust on it, so I just dipped it in water to clean it up, now there's some water artifacts on it. Its inside the lens I'm guessing. Been a few hours now, how long do I let that dry? Or do I have to buy a new one? I can definitely feel a reduction in burning power.

Just got it. Great looking pen. Might use the host for something else in the future. Not bad, a relatively "safe" blue pointer.

So I was just refunded on my 2 OD7+ goggles due to some issues. I'll order these again in a few months, not right now. Will the 190-540nm OD6 from Survival Lasers be good temporarily for a 7W 445nm and 1W 520nm?

So, I received my 2-2.4W laser from Sci-Fi Lasers. Currently my most powerful laser since my 2W broke. I own a few other 1W blues. Waiting on the 7W. My communication with Eitan, compared to others,was perfect. He replied to everything and almost instant. Your case might be different but I had...

I just made this. Because. Just tell me what you guys think. Original picture credit goes to TunnelCavityLasers

Do you guys travel with your lasers and if so how do you deal with it? I'm into photography, I was thinking of taking them with me to take some nice landscape pictures. Seeing as the Arcane 2.0 looks like a big heavy flashlight, I'm guessing without the batteries it'll pass security quite...

I just ordered the new 1W 520nm from Sci-Fi. That, plus the 7W + 2X 0D7+ Googles @$149 EACH = $1048. Getting almost as expensive as my watch collection, well...not even close, those are in the thousands but still..Damn. And I gotta get that 589nm from DragonLasers soon. + NUBM06E or 08E Bank.

No longer available.

I just bought this, claims its a 5mw. I don't have a meter but..anyone? I can't compare it with my 50/150mw greens because I broke them all. And my 1W 445nms are not with me at the moment. Was $20. Looks like a generic pointer. Worth it or not? I don't actually own any low powered lasers...

Just thought I'd do another update to my aliexpress blu ray laser. Refer to this: http://laserpointerforums.com/f44/0-02mw-405nm-violet-laser-damn-you-aliexpress-96415.html Anyways. I got a message from AliExpress and they told me that they ordered the seller to remove ALL his laser sales...

Move to 1:40, watch the objects to the left. Someone>Obviously UFO trackers>Govt> Fires a "beam" of some sorts at them and they, as you can clearly see, evade it. Now, what do you think that could be? Powerful enough laser to reach space? Or any new weapon? New as in secret new as this was in...
