they are coupled together...
I paid $3,800.00 per diode. Compared with +100K for a decent fiber laser machine. I think that it is a very good deal.
On top of that, if you build your own machine it is scalable.
And you do not have to buy all the diodes on one shot.
Damn, that's still a chunk of change. I'd like to have a lighter-duty machine to cut carbon fiber layups, not sure if the wavelength's right for this application, but at least just one 70W pump would likely be enough.
Interesting, a quick check brings up these guys: Carbon Fiber - Laser Cutting and Marking Carbon Fiber | ULS who recommend a hybrid of 10.6u CO2 and 1.06u Fiber for pre-preg.
How are they coupled together?
You can get equally powerful CO2 lasers for much, much cheaper, though I'm not sure at what price point beam quality would be the same.
Thanks for the link Milland that's interesting. We may end up soon needing to make maybe 60-100 pieces of prepreg for a small lay up (~6"x12"). We have access to a 60W 10.6um Universal VersaLaser for nonferrous and our in-house waterjet (which could actually work fine if you sandwiched a stack of pieces). I'd be curious if the CO2 laser by itself will work or you really need the hybrid technology as described in the link.
Since we are all here, Milland, can you speak at all to laser vs CNC knives for carbon fiber? I could see the knives working better on plan cloth where they might have trouble with prepreg? Those videos of F1 teams and such show lots of knives but perhaps this is all rather 2006 and if you started now you'd get a big table 70W laser?
Since there seems to be a bunch of people up on their laser info. Can anyone tell me what frequency/wavelength and wattage would I need to get deep etching (~1/32" need it deep enough to hold the engravers wax (or whatever they call that crayon) and up to 10ga piercing (even if 2 different wattages) of 304/316 stainless?
I've been looking into them for a while and can't seem to find that bit of critical info, or when I did, sites were disagreeing on the wavelength.
At work we still use an electro-etch with the blue impression paper, hand stamps and a pantagraph style New Hermes engraver for marking equipment. Probably we are one of the few offices within a 30 mile radius that has a manual typewriter still in use... Their paid for and they work great, but it would be nice to upgrade, if we can afford it.
Does anyone make a variable frequency laser (without it being different laser modules)?
Very nice! I want one...
How hard would it be to hook up more diodes for more power and/or whats the theoretical limit on power from linking them all up?
