Do you think it's possible to turn up the power on the 400mw beam corrected spartan? I saw the beam of an arctic and it's horrendous...

This also broke the camel's back.
Dear URANIUM

First of all, we would like to apologize for all the delays and any inconvenience.

Upon checking for your order to get ready for shipping, we have received an information from RBS worldpay that the payment has already been expired due to being pending for a month.

If you want to continue with your order, we would need to ask you again for your card information so we can reprocess the payment of $218.06 for your order. Once we reprocess the payment, we will keep your order on high priority to be included in our next shipment.

Best regards,
Customer Support

So is it possible to turn up the power on the spartan without blowing the diode? Maybe use a drlava driver. And most importantly, CAN YOU OPEN A SPARTAN?

If not, i'd like to commission someone to build me an 800mw handheld beam corrected 445. I would do it, but I don't have the cash to accidentally blow an a140 diode. $220 is all i have.

Great -- so this is actually going to be the case with *most* early Arctic orders. My RBS Worldpay charge was certainly more than a month ago.

"High priority" -- I'm sure... At least they're not charging you the new price.

There ARE ways to open CNI hosts, but it's not easy... Keep in mind the beam corrected version is probably set at 400mW for a reason...

The Spartan is made by CNI, therefor it is a CNI host. They're difficult to get into, was his point.

I think the diode is being pushed to the limit already to compensate for the correctional optics' losses, I have doubts that it would be able to go much higher...

Some DIYs with great heatsinking have been pushed to 1.1 or 1.2W, so assuming these are taking full advantage without risk of this diode's potential, minus loss for beam correction; 1W - 600mW = 400mW (spartan's power)

and if you push it 1.2W - 720mW = 480mW (spartan's theoretical highest possible power)

(60% loss in optics?)

Okay. The Spartan is a CNI PGL-III-M. The front cap should come off, and all disassembly would have to be done through there.

You'll need a lens spanner. And it'll be tricky. And there's really no guarantee you'd be able to pot-mod the laser (which is essentially what you're hoping to be able to do) without damaging it.

The reason that CNI (and DragonLasers) has the 'corrected' version set to 400mW is likely because the optics themselves or the coatings can't take 1w.

But, you'll have to likely unscrew the front lens retaining disc (or front lens disc itself), and take the module apart layer by layer until y ou get to the driver. The entire front driver module may be pressure-fit, but CNI mought have put some glue in there to secure it.

In short, I'd say trying to turn up the 400mW is a bad idea.

We're not saying they suck 600mW. We're saying they may start to degrade, darken, or deteriorate when exposed to >400mW. There's absolutely no reason for CNI to set these lasers at 400mW if they don't have to. It doesn't save them any money or make them any more margin/profit. If it's set to 400mW, it's set that way for a reason.

What do you guys think about using a Casio A-130/140 Diode inside a Spartan Body? It would be nice to crank that 1W up if you had the proper adapter and dragon lasers beam expander :)

I was eying the green 30mW spartan, as it is the cheapest spartan and use it as a host for my A-130

Though with the 400mW 447nm spartan being only $20 more then the 30mW 532nm, It may be worth it to get the 400mW 447nm spartan just to have those extra internal for a different project once your done making the A-130 Spartan :)

The Spartan 447 *is* using that diode.

Acrylic? :yabbem:

Could be. Could very well be, at that power limitation. I'm sure there's a glass lens in there somewhere, but there could very well be an intermediate acrylic aspheric element.

Then i guess I'll wait to see if something better comes along in the future. :( I doubt anyone will be machining laser hosts with those correcting lenses (i saw for sale here) anytime soon.

Things happen pretty fast around here. Just in 2010, we've seen 671, 589 and 445 portables happen. Two years ago, 20mW of 405 was impressive.

445 is pretty young as far as the hobbyist scene goes. I think we'll see a lot more.

Where was this announced? I was under the impression that Dragon Lasers was using the CNI GB Diodes. The specs may be close or similar, but the manufactures are different, as the Casio Diodes are made by Nichia. We already know the Casio/Nichia Diodes can be pushed past 1W, though we do not yet see what degradation affects running them that high has on them. The CNI DB Diodes are more established, and I would prefer not to pump the power up on those.

The CNI Group Buy Diodes? Huh? What do you mean by CNI "GB" or "DB" diodes?

CNI and Casio *most likely* both use either Sanyo or Nichia diodes. CNI is not making their own diodes for these. (That'd make no economical sense at all. Even their DPSS pumps are Osram or nLight.) Wicked harvested them from Casio projectors, and CNI likely placed an order with Nichia or Sanyo, but in either case, chances are, they're the same diode. CNI units are available at 1W. Casio-harvested units are available at 1W. DragonLasers (CNI) units are available at 1W.

aryntha; I believe he was reading only the title of Glenn's newest GB, and was led to believe that the 447nm spartan had a CNI diode in it due to the advertised differences (i.e.447nm rather than 445nm). :)

SpartanX; No, the spartan from CNI uses the same diode as everyone's DIY lasers and all of WL's arctics, the only reason 445nm diodes are so cheap is because casio purchased them en mass for their line of projectors, each of which has a diode bar with 24 of the 445nm diodes on it. :)
