Here's a cutie. I have been playing with it all weekend :)

This is an A140 diode in an old style Dorcy host. It uses a flexdrive. The Dorcy is powered by a single RCR123 battery (3.7V). It is producing >600mW with the AixiZ 445nm Glass lens. If you get a 405-G-1 lens, it will go >700mW.

The laser comes with two batteries (so you can keep one charged up) and the AixiZ 455nm Glass lens. It is $215, shipped in the US

Re: FS: >600mW 445nm Dorcy

I'm curious since I wanted to try a 445nm Dorcy as my next build, what did you set the driver to? I was wondering what the max current draw is from a RCR123a and how high you could set a flexdrive or a microboost to in mA. Thanks for any help.

I adjusted this one to output NOT input. I set the range on the driver and cranked it up. Then I turned it down until it didn't heat up very quickly. At 620mW with the Aixiz glass lens, I would estimate it at about 700mA

It's got a 1000mAh LIR in it and has been running just fine all weekend

Peace,
dave

Re: FS: >600mW 445nm Dorcy

At first I didn't realize what company LIR was, until I remembered it on DX. And thanks Dave, I really appreciate it. I'll probably set mine to around that when I get the host.

Funny we have the same join date, yet you got over 20x the posts and well over that on rep ;)

LIR = Lithium-Ion Recharcheable

I'll be willing to buy this, in a couple days, if you link me to a pair of safety glasses suitable for this.

Re: FS: >600mW 445nm Dorcy

What's the duty cycle on this?

Also, do you have any less powerful builds?

These diodes are too new to be to be able to answer your question confidently. However, I can tell you that, in the projector, the thermal protection circuit is set at 100c (212f). That means that they can run pretty hot! As long as you turn it off when you start to feel "warmth" I would not be worried about it. The power tends to drop as the didoes heat, but that is normal for these

How low of an output were you looking for?

Peace,
dave

Re: FS: >600mW 445nm Dorcy

Well here's my deal:

My first laser was a 532nm 50mw, and I've had that for a few months. I didn't use goggles because I only shoot it at night up into the sky...never up close.

I work in a laser facility, so I'm used to using goggles there, and now I'm looking for the "next step up" for a laser.

I'm just not sure if 600mw is too much. Maybe it's okay, I'm not sure. Obviously I'd want some OD5/6+ for closer use, but do you think I'd still be okay with it for beamshots?

Basically I don't want to sacrifice being able to shoot it into the sky at night and show friends. I'm worried that the safety issues with a really powerful laser might take the fun out of it.

Thoughts?

EDIT: DJNY: I would probably just go for the cheaper version, as I'd just as soon buy from Daguin as dish out more for CNI. Thanks for the link though ;-)

If you only use it for shooting it up to the sky or at objects far away (non reflective), you don´t need googles. But if you want to use it inside, buy some.

You'll be fine using it outside pointing it into the sky. Just don't let your friends handle it if they're stupid:crackup:

Re: FS: >600mW 445nm Dorcy

Okay, cool. I think I might go for this then. I'll think about it for a few hours though =P.

Daguin: one last question for you. Any chance you've made any calculations to determine beam waist and divergence? I ask because I need that to throw into some software I have to determine optical density requirements.

Thanks all!

Go with OD 4-5 certified goggles ideally - 3 is the very minimum you should be using with these.
