Yes. (You can't get red out of 808nm IR.) CORRECTION: you can (thanks for the correction, TJ), but I don't know if you want to spend over 1000 dollars for 100 mW of red (see http://www.optotronics.com/671nm-red-laser-systems.php ). If by "glasses" you mean something like this, you should be...

I once thought about that too, but the fact that we'd get a super-hot beam stop convinced me it was not the way to go. Then I saw a video about creating plasma with a laser and came up with a different design (see attachment). What about that? (yeah, I know it would need a LOT of batteries)

I would've told her: "Wanna see this laser burn a hole through stuff?", told her to put on a pair of laser safety glasses and fired the laser against a light brown carton box. Cue a burned hole in the carton box and a 9 years old girl scared out of her mind.

Spikes of current, current too high for that particular laser, temperature too high. Also, I read a post about an argon laser where it was said that if it hasn't been activated for a long time, it was probably unable to be activated again. Why does that happen?

Can gas lasers be damaged as easily as diodes?

Re: Coolest experemnts you guys have done? I focussed the beam of my new style dilda on a ligh brown carton box, expecting most of the beam to be diffused away, but surprisingly I was able to easily burn holes in it... and even write words on it, if I moved the focussed spot quickly enough. On...

So far, I only used my new style dilda to see how different materials would react to a focussed beam (and surprisingly, I found out that it's very easy to burn light brown carton, while a black liquorice candy is almost impervious to any effect). And, as BKarim says, it would make a cool...

How can you have a Voodoo 7? The last generation of Voodoo cards was 5; the next generation, codenamed "Rampage" never came out because Voodoo Graphics went bankrupt in late 2000.

I wonder if yours is a rhetorical question, given your number of posts and reputation: in that case, my answer will be rhetorical as well. Powerful IR lasers are cheaper than visible lasers of equivalent power, so, if someone wants to use a laser to cut and burn stuff easily, an IR laser will be...

Thank you for the exhaustive reply, Daguin. Yeah, I figured out my question was off-topic in this thread a couple of seconds after I posted it, when I read that the thread was only about 12x diodes. :oops:

Did anyone ever try this Blu-Ray diode from O-Like? Is it really 300 mW? If it is, why aren't they selling a 300 mW Blu-Ray dilda laser too?

I ordered it on January 19 (honestly, I'm surprised it arrived so soon), and I have two questions about it. 1) the battery charger is provided with a standard US-style plug, but I live in EU, which has a domestic voltage of 230V, as opposed to the 110V standard of the USA. Does this mean that I...

And I just did the same on ANSA (the main Italian press agency). As you say, it does not mention any ban. It just says that the people responsible for shining laser beams at planes have been reported to the police.

I heard the news: please correct me if I'm wrong, but apparently, the ban is limited to the highest-power GREEN lasers. The newscast I heard specifically mentioned green.

If she does not, would I be right in assuming she was unable to reply (or even unable to read my message) because, when the site is down, so is the mail server? UPDATE: Susie replied, said that my order was shipped and gave me the Hongkong Post number to track it. Now I just have to hope that...

I did that about a minute before posting here.

I ordered my new style dilda on January 13, and I almost immediately received the order confirmation, where the reply said "We will ship it a.s.a.p then let you know when it is shipped". As of today, I still haven't heard anything else from them. Is it normal?

I recently bought a Kingston DataTraveler USB pen drive and tried to transfer some big files from a CD to it, and I noticed that the same files are transferred much faster by copying them to the hard drive first and then transferring them to the pen drive, rather than copying them directly from...

Is there an alternative to eBay? As in, an actual online store that sells good quality batteries and chargers?
