"Blue Demon" & "Green Demon" now available - 15W Blue & 4W Green Handhelds

[Unown (WILD)]

Alright, the moment you've all been waiting for is finally here!

I had a few minutes tonight to tear this thing down. After trying better batteries on the blue pointer I still wasn't getting any better output so I chose that one to disassemble. I first disconnected the diode leads from the driver and tested each diode separately. As I suspected, one diode worked and the other didn't. Not even a glimpse of blue emitting and the power supply showed no current when connected so it was a wide open circuit. I'm guessing the Chinese didn't even bother to test this one after it was assembled.

I first heated up the top cap of the pointer at 600 degrees F with my trusty heat gun. I was able to break it free from the Chinese laser pointer glue and unscrew it fairly easily with a silicone rubber jar opening grip. The final optics assembly came out very easily and I was surprised by how much Chinese laser pointer lube was inside just millimeters from the lens. I cleaned up the globs and went to work on the rest of it. I heated the crap out of it at 600 degrees and it just wouldn't budge. I finally cranked it up to 800 degrees F and finally broke it free using 2 pairs of Channellocks. That piece is marred pretty good but it'll buff out after I throw it on my lathe.

It looked like the diode module assembly was also glued in but the immense heat allowed it to just be pushed out easily from the other end. There was a little bit of thermal paste on it that I wiped clean. I then removed the 2 tiny little Philips screws and popped the top off the module.

There are two "G-Ball" diodes in the module so they are definitely not NUBM44 diodes as previously stated. I was told they are NUBM0F diodes and that makes sense because they do have close to 7 watts output which rules out a NUBM08 or similar diode. I may replace one or two of the diodes with NUBM0Gs and see how that works out. A mixed color output might be neat but who knows.

Here's the album of all the photos I took: https://ibb.co/album/8YFjSy

Thank you so much for this! Yeah you should use a green and blue for a powerful cyan laser

So absolutely nothing special, just a polarization rotation plate and a polarizing beam splitter (e.g. a combiner here).
Looks like they use FAC diodes to get the beam to acceptable divergence.
Edit: too silly to read
Beam must be quite bad than?

 

[Gryphon]

Well that's a shame that one of the diodes was a dud right out of the box. Is all the alignment and aiming of the lasers for proper overlap done with the single combining element?

 

[RedCowboy]

Yea, the angled optic ( right optic ) is a polarization pass/reflect element, just not square like we're used to seeing and the optic on the left is a wave plate that rotates the polarization of the left laser so that both lasers can be orientated the same, so they will perfectly overlap, the right element combines the beams via polarization ( pass/reflect ) .... so the right laser passes through and the left laser reflects due to the wave plate rotating it's polarization.

I can’t say I am dissatisfied with the 4W green that I purchased from them being a Chinese build that they do at least offer at a fair price as compared to their competitors (Zeus, Gravitas..). The built-in optics are good even though the host aperture doesn’t allow for expander attachments. The automatic shutoff annoys me a little. This is the laser focused at a 24,000ft cloud ceiling at about 45 degrees.

A couple clearer shots of the 4W green. Impressive especially when I think back to when I first sought to find the most powerful (50mW) 532 unit of the c2000 era. This is the first high-power handheld that strikes a bit of fear, and certainly respect, in me. Much like that of my Colt 45. In some ways I can’t believe anyone (Anyone) can buy something like this off eBay now.

Thats nice. I want to get one, but what size is the host? What diameter is the beam? Does it allow focusing? Is it just 1 beam or multiple diodes inside?

You can start at page 1>2>3 and read the comments it describes everything hope it helps

I got one of the Blue demons in my order from tinker. When I got it I was skeptical that it was actually 15W. It burned better than my 7W, but only marginally. I also couldn't see any sign that it was two beams overlapped when I defocused it, which made me think that either they aligned them perfectly, or more likely, one of the diodes was DOA. Finally got home to use my LPM a few days ago and sure enough, only about 8W out. Returning it and hopefully I don't get unlucky again.

I like the laser, it takes lots of turns to focus but this allows for finer focusing. I too have never had such huge batteries, I thought the 26650s were big.

I also agree that a tail switch would be safer, but I suppose it does at least have the end cap that screws on.

You can get them from China directly for a lot less money. Tinker is mostly just reselling Chinese laser stuff.

I see. I'm guessing the diodes don't have modules with copper back halves like DTR offers. It would be cool if they did and if that block they're in was copper

Read back in this thread and you'll see where I posted photos of the complete disassembly of it.

 

[Shakenawake]

I saw those but can't see what kind of module the diodes are in or the back of them

 

[Shmackitup]

They're directly in the block, not a module:

 

[Shakenawake]

I see. That makes sense sense you wouldn't want it spinning in place even a little

Lining it up might be more difficult this way. You probably don't get any do overs.
