I am just buildin a little rig to play with one and I intend to kill one at some point (prob. sooner than later ) My intention is to kill one not to kill accidentally - we will see what happens first!

This is going to be good.

Jesus wept this thing is bright.

Here, have some pictures of my experimental rig:

They are pretty amazing aren't they? How hot are you running it? What lens?
I melted an aixiz acrylic with mine. They don't like a watt.

I've got some kind of random Aixis 405 lens in it at the moment. Seems to be fine at 560 mA. I don't want to run it any hotter than that until I have a better heatsink arrangement than "oh hey maybe I can use some of this indium foil to shim out an aixis module to fit an old ScanPro galvo block... have a couple of those... and then sit it on this here TEC... and where did that nice copper heatsink I had go?"

[chad]

lol,ok.

From what I gather, so far the best cheap lens for these seems to be the aixis glass 405 lens. I should pop mine into my 405-g-whatever and give it a try but It is running fine in my tec test rig And I still love to turn it on and see the powerful beam.

It was REALLY foggy around here late last night. And I so wanted to blast it outside. But I fear I would have woken up my neighbors with the blue glow.

Mine has been set at one watt from the first time I ramped it up. Still going fine. ~10 hours.

Is that odd square a camera artifact or back reflection of of the die spacer (whatever it is called)?

That's what it really looks like, except it looks bluer.

Also, I couldn't resist:

[chad]

hhm, that is really strange I don't see that in mine.

Oh well.

I may not have mine pressed into the aixis quite exactly straight...

LOL someone's burning stuff! I want to see it lighting matches!

That reminds me of an old laserium effect calld the "burn wheel". It did just that.

I have seen that around here a couple of times, mostly by accident though. I have a nice little divot on one of my monitors.
