SOLD: 445 Single Mode Build - 450nm 150mW - (Highest Powered SM Blue Build So Far)

Sad to sell this guy, he's my only single-mode build right now. To clarify for anyone that missed it, this is a single mode diode. Meaning it has really good beam characteristics. Unlike the "rectangular beam" 445 multimode diodes that we're most familiar with, these single mode diodes produce much more of a proper round dot.

I really like this build. It's a great build that runs off 2x CR2s (rechargeable 3.7Vs are recommended), and uses an "X-Drive", the amazing buck driver from Lazeerer (NOT to be confused with the Chinese cheap laser seller of similar name). It should also work on 3x 10440s. Since this is a buck driver, the extra 3rd cell shouldn't create any problems, or impair efficiency. If you want to go that route, please remind me to include a 3x 10440 carrier for you. If you Seriously, that guy deserves some cred here - I love his driver, it's a fantastic buck driver.





This build uses an acrylic lens - at this power, with this diode, it has better characteristics than 3-element glass. It is outputting 150mW (it's quite an efficient diode for a single mode). It uses the slightly more expensive O-Like diode (pricier than the Rayfoss). I have spectrometered it at 450nm, that's not an estimate.

Re: FS: Single Mode Build - 450nm 150mW

Are the o-like and rayfoss actually different diodes, or is the o-like one just more expensive?

Cool that you got that spectrometer working. Good luck with your sale, I like that host!

Re: FS: Single Mode Build - 450nm 150mW

I thought they were the same, but the o like seems to handle higher current than the rayfoss. Hardly a large sample size though.

Re: FS: Single Mode Build - 450nm 150mW

Cool, Ill keep that in mind when I finally get one

What current are you running this at? (I don't think I've seen any graphs on these yet)

Re: FS: Single Mode Build - 450nm 150mW

IIRC correctly, it is running at ~200mA.

Don't quote me on that one. There's no way for me to double check (tailcap current, etc) since this is a buck driver. I wouldn't want you to try 200mA and find that it kills a diode. But I believe that's what I'm running this at to get 150mW.

Re: FS: Single Mode Build - 450nm 150mW

@benmwv, I have one of those o-like single mode diodes if you would like to take it off of my hands, O-like accidentally shipped it to me instead of the complete laser I ordered. I don't have time to build anything at the moment and I would be willing to let it go for a far price.

I think the host itself was also a Lazerer (ARRGGHHHH - EDIT: "Lazeerer") creation, if I'm not mistaken. Is there anything that guy doesn't have his hands in?

NOOOOOOOOOOOOOOOOO, Lazeerer

God damnit, it doesn't matter HOW CONSCIOUS I AM of the difference, I'm always going to screw that one up. I think I'm doomed - a lost cause.

Why the hell did they have to co-opt his name? This drives me nuts. Nuts I say!

Can I run 2 x 16340 in this?

Thanks,

If they'll fit, then yes, certainly.

I think I put a CR2-designed battery sleeve in there that you'd need to remove. But other than that, yep.

Just make sure that it doesn't put too much pressure on the head spring and driver area.

Doesn't look like they'll fit... Off to Amazon or EBay. That was fast shipping BTW!

Did the wavelength shift when it is overdriven at 150mW ? I have ordered the diodes and I was wandering if the wavelength is the same at nomimal 80mW and overdriven 150mW.

Sadly, I didn't have the spectrometer prior to setting the current, so I don't know.

Just an update, I put a 405 G-1 lens on this thing tonight and got 190mW with a quick test! It was metering exactly 150mW with the original lens! :bowdown:
