Mass buy of 445nm lasers...

[jcswimmer305]

Hey guys,

I've been looking at a bunch of websites trying to look for cheap blue lasers (weak, like <5mw, and already assembled) to buy in mass.

I haven't really found anything, and they need to be specifically 445nm. I've found 360s, 405s, and the 445s i've actually come across are too expensive for what I plan to do.

I really just want to take apart the laser so that I can play with and experiment with the diode. I'd really prefer 445 over 405 though.

If anybody knows where I can get a bunch for a relatively low price (about $3-10 each), I'd be really appreciative to know.


Thanks!

such an item does not exist.

lasing threeshold of the current affordable 445s is ~200 mWs... no less.



and I gotta ask---why?? would you want to do this?? makes no sense..

Oh well, I'll just buy a bunch of wealkreds then.

Reason: I learn better practically, meaning hands-on, than by just theory and reading.

Then red is definitely what you want to be playing with... Just be careful, pinouts for Reds and Blues are different.

Hak, I don't think that's accurate. I lased an A130 at 119mA and it lazed, but it was about as dim as a LED'ed phr diode. So if you're looking for a blue pointer, you could theoretically do it, although it'd be very dim unless you lazed it around 20-30mW, and it's probably look better with the 0sr4m single modes.

Also, what was the price for the 360nm's?

I can tell. I've seen all your threads and you have absorbed nothing since you have been here.

You have to read. There is no way around it. There are to many variables in lasers. You cant just rip a few apart and lean how to build lasers. You have to know what combinations work, and what doesn't. You cant do this cheaply. You have to learn that stats on each diode, and on each driver. And how to set the driver to what you want it to do.

Your best bet is to buy a kit, and get the drive preset to what you want for the diode you are using. If you want a low power blue get the driver preset at 200mA. If you want a burning blue get it set at 1.4A. just tell the person you are buying the kit from what you want, and they will help you.

If you still want to go hands on, pick a color, then read, read, read everything you can find about it. It will save you a few bucks.
