Finally got around to wiring this up. Very beautiful color. It's a little bit over focused though. I'll open it up soon. Thank you ^.^

I do not recommend heating the host unless you have an extra diode sitting around. Heating should be a last ditch effort

It might be sealed with epoxy, but typically they only use some kind of sticky thread lock. With enough torque you'd probably get it loose. I've gotten hosts unstuck by using a heat gun / hair dryer, but it killed the diode Edit: You got a strap wrench? I edited my last post. They come in so...

That tube is one big solid part. The copper heatsink is pressed in there, and fits by friction. You would have to get a pipe with an outer diameter slightly smaller than the laser body's inner diameter; and the pipe's inner would have to accommodate the driver so it doesn't get crushed. Then...

If you use a laser as a self defense weapon, WEAPON, you will give lasers and anyone who uses them for innocent fun a bad rap, and then no one will have lasers. You should rethink this and get a stun gun or something you won't go to jail for using in self defense for.. like a gun or something

laserbtb 20->50mw(when hot) It's just *that much more of a minty green color than 520. You might have a better chance of getting closer to 510 if you underdrive it at 5mw or 1mw instead of 30mw

Re: WTB: A140/A-type 140 Laser Diodes Gotta wait until they're in my possession. I wouldn't feel quite right selling something I don't have yet

Re: WTB: A140/A-type 140 Laser Diodes WOOO ^.^ I did it. I won. The estimated arrival date is 16 September. So, officially, anyone want to reserve one? If so, state the quantity and I'll PM you when I test the diodes. $25ea+shipping ($2.54 US / 6.39USD International). They'll be shipped in...

Re: M-type M140 Laser Diode Giveaway :gj: +rep [skip me if I win on accident]

Re: WTB: A140/A-type 140 Laser Diodes I'll certainly take reservations, but I'm not promising I can win this auction. I have a pretty good chance though

Re: WTB: A140/A-type 140 Laser Diodes bid placed. we'll see where this goes

Re: WTB: A140/A-type 140 Laser Diodes yep, I can't buy the projector

Re: WTB: A140/A-type 140 Laser Diodes Hmmm I would have to do $25/diode + shipping (2.54 inside CONUS; 7 international) I never sold diodes before. Does that sound like a good deal? I'm just afraid to spend $300 and not get it all back. They would be used diodes with 4000hr runtime by the way

Re: WTB: A140/A-type 140 Laser Diodes Ok, last call for offers, if not I'm just gonna go ahead and drop the cash on ebay. I had built one in a very nice ebay host, but unfortunately the driver I had on hand wouldn't do any less than 0.7A. I'm planning to get a 0.2A driver for a new one in the...

Re: WTB: A140/A-type 140 Laser Diodes Yeah, that one. If only we had more data on wavelength/current

Thank you all for your input. I can get them for $30ea on ebay. This thread is just for offers if anyone has some they don't want. What I really want is to underdrive them to get like <440. Alternatively, does anyone know if those old 2.5w 9mm Nichia diodes have the same characteristic? It's...

There's a clear difference in the color of those A140s and other blue diodes. The A's seem to be true 445nm and the M140s are 450nm, as is evident when comparing them to PLT450B diodes. Indigo is my favorite color. I really want some true 445nm diodes so I can preserve the wavelength for the...

Just waiting for some terrorist organization to invent a T virus

Yeaaa, my diode still had like 0.5mm of play judging on it rattled about when I shook it. Oh yea, and thank you for your thread. I might not have figured it out for another day without you +rep

Welcome to the forums. Please go to the Welcome Forum and post an introduction thread. The only advice I can really impart onto you about that is that you should never have batteries in that laser when you're working on it. If you had no lens in it and turned it on, the laser light would spread...
