No, the days of getting excited waiting for something are behind me. I used to, when I was about half my current age, but now I only get excited when I actually get something, not before, even if I absolutely know that I'm going to have it, and no matter how much I want it.

Typical sensationalistic story to impress n00bs. Let's put it back into perspective. This means that if the pulse lasted 1 second, it would emit 1000000000000 joules of energy. But it doesn't. It lasts only 0.000000000000001 seconds, so it actually emits 1000000000000*0.000000000000001 = 0.001...

One of the comments says: and another one replies: That's not entirely accurate either. It's like nobody has ever heard of burgers until some crazy dude writes a story where the characters eat burgers, people love it, then scientists find a tiny piece of evidence that might lead to the...

Well, yeah, that would work, but... it would sorta feel like a copout. Like buying a more powerful PC to get more FPS in games, instead of overclocking your current one. Ah... that makes sense. Where could I find those drivers? And would each of those require its own battery (or set of...

Pure and simple curiosity. I'm curious to see for myself what exactly a fast-axis-corrected, focussed infrared beam can do to various materials, as well as to see how big a battery-powered IR laser of that power would be. Why, just because you can't see the beam? But I never see the beam when I...

I was thinking about a battery like this, unless the driver reduces the voltage too much.

Some sites, like O-Like, sell complete 808nm laser systems (diode, heat sink, fans, driver). But what if I want to buy the driver only? Googling "808nm laser driver" got me some results on Ebay, but those drivers only go up to 1W. So, let's say that I want to power a diode like this. Where would...

I think there will be a fall in handhelds and a rise in labbies, because of changing laws.

Wickedlasers is all about selling overpriced lasers that look cool to impress... um... impressionable people. It was Wickedlasers that advertised 1W 445nm lasers as lightsabers in 2010 and caused a media backlash where news sites were talking about "the Chinese selling real lightsabers to kids"...

LOL at the description:

Oh yes. (I was going to post just "yes", but the forum won't accept posts below 5 characters)

Impressive. But that makes me wonder: if the resulting green beam was 12W... how powerful was the original IR beam? :drool:

Oh, now I see it! I was looking in the wrong place. You're right, the picture of the original object I posted doesn't show anything of the sort. I'll ask the seller for explanations. Yes, I know that part of the theory. :) What I lacked was information about the look and position of that lens...

So I searched "FAC lens" on Ebay and found this: 5W 808nm Laser Diode C Mount with Fac Lens | eBay I suppose the gray half-cylinder in the corner is the FAC lens, because I searched "c-mount laser diode" on Google, and the diodes in the pictures I found don't have that part. I wonder what...

NOTE to anyone reading the post I am quoting: in case you cannot tell, IT'S A JOKE. Nothing can create the effect of a beam "glowing black" or "forming a shadow". 808nm infrared light is perceived as very dim red, but looking at the dot of a high power 808nm laser without protective goggles...

I would never bring my lasers to the bathroom. Too afraid to get them wet. Also, bathrooms tend to have mirrors, and I'm a strict observer of Niven's second Known Space law, except when using optical media (who gets the reference? :D ).

"Win-Win-Mechatronic", an Ebay seller from China, with 99% positive feedback, is selling a 40W CO2 power supply at $110 and a 40W CO2 laser tube at $120. Has anyone here ever done business with him? If the answer is yes, what were the results?

Sorry if this is considered necroposting, but I was looking for threads about C-mount housings and I found this one, which surprised me in a good way. Until now, I thought that a "weird" shape like a C-mount would need a strange and expensive housing... instead it uses the same kind of heat...

Oh, so that is why. Thanks. EDIT: However, if I may make a suggestion: if a search query does not meet the limits of the search function, the resulting message should say so, instead of just saying "no matches".
