Here's some pics. of my first 445 build.
I decided to make it a labbie until I get the heat and current demands worked out.
Output is around 900mW using a stock Aixiz lens. I am sure it will top 1W with the glass 445nm lens from Hak. I have already melted a stock one. Burned to a crispy blob is more like it. LOL

Driver is Flex V5 set at 950mA, cooling is accomplished with two 20X20mm fans and one of my custom finned Al. heat-sinks.
I made it duel powered, using internal batteries or with the flip of the switch and a phono. jack it can be ran with a external PSU.
The fans also can be controlled separately. That way I can leave them on after a duty cycle to cool everything down. No waiting 2-3 minutes between duty cycles.
For right now I am using 3 AAA batteries to power the internal power, only because I don't have any 18650's yet. (some ordered)
I am going to use three of them in parallel for plenty of run time.
Using the AAA's, my run time is <2 minutes before output starts dropping.
I will also add a external recharging port, once I get the right batteries.
Alright here's the pics. Outside and inside.








I know it's a little crude, but I wanted to see those blue photons quick.:whistle:
The next one, I will take my time with and have a much more professional looking unit.:yh:
:thanks: for looking.

Sweet build. A portable labby, looks really clean :yh:
Got any beamshots? Outdoors maybe?

Sweet.
I'll be working on my labby soon, when all the parts come in.
till then, impatiently waiting.

Not yet, but I will get some shortly. I am waiting on a foggy night. (and my glass lens)

Nice labby!

It says Class VI on the label though? :D

Is it an A-130 or A-140 diode?

:thanks:
Yes, I thought twice about putting that on there. If I was out somewhere with it, I could not claim it was 5mW.
But, WTH, it won't leave the house much. And when it does, it will be well buried in all my other stuff.
It is a A-130 diode.

He was trying to point out the fact that it is a class 4(IV) rather than a class 6(VI). :p.
I didn't even catch that till he mentioned it.

Good re-catch.
I didn't understand when he first mentioned it, dyslexia? :undecided:
Thanks for pointing that out... class 6? :eg:

Oops! I dropped the ball on that one. Thanks for pointing that out. I'll have to make a new label for it. Good thing I'm not a Roman:crackup:

I think Rome would have burned sooner if they'd have had these! :crackup:

^Yup, this. I remember a post when these first came out with the same easy to make error. Someone posted, "We now have class VI lasers? :eek: " I wondered if it would come up again. No biggie, I thought it was just a transposition error.

I still think it's a nice labby!

I'd leave it as a class VI. It has a custom look to it. LOL No one will doubt it's at least a class IV at those power levels anyway. As far as I know there isn't a higher class than IV, but I'm going to look that up. ...............Yeah, so apparently class IV covers military grade mega watts too.

Nah! I had to fix it. Can not have inaccurate info. on one of my lasers. I read somewhere that the FDA is using standard numbers now anyway. I hope so, because that's what I used this time.:undecided:
I can't remember the last time I used any Roman numerals higher then III, so that is my excuse. I mean come on, how often do you all use them in the real world. (other then here)

Lots of beam shots to come, as soon as I get my 445 lens.

thanks a lot. I love seeing the everyone's designs. this works and it's close to what I may do with an extra 445nm i bought. waiting on my hak lenses as well.

Despite the fact that you consider it "a little crude" it looks fairly neat & clean to me. :D

How noisy is one of those fans? I'm adding a couple to my allelectronics order. Are yours from there by the way?
