My 1.6W G84 Tri-Beam Red Laser!

Okay so I just wanted to show off one of my more unique recent builds
This is a Mitsu G84 diode with an X-Drive set to 2.4A. I got the diode from our friend Podo and the driver came from our other friend DTR

The host is a full aluminum host that holds two 18650s and has a rear clicky switch. This host was made by our very own ElectricPlasma! So far I have had 2 hosts made by him and I gotta say that he does a superb job and I'd definitely recommend him if you're looking for a custom made host!

The focus adapter is full copper and was created by FlaminPyro. I am amazed that he was able to create exactly what I wanted because the only thing I gave him as a reference was a crappy MicrosoftPaint drawing :crackup:

So I thought that the G84 could hit 2.5W but mine only barely hits 1.6W. Maybe if I get a bigger driver it'll go up in power but I don't know enough about this diode to try and push it. Either way I'm happy with it

Here are some pics (I skipped the build process cause it wasn't anything out of the ordinary)

My iphone doesn't capture how sharp the lines actually are on this thing

The adapter in action!







Sooooo there we go! I'm gonna be playing with this thing all night

I hope you enjoyed it and maybe we will start seeing more of this diode, or others like it (I'd sure love a multi-emission green or blue)

Awesome build, cool diode and cool host!

The adapter is a nice touch!

You should post over on /r/lasers too - that sub needs more activity.

Are you using a lens? If you are what effect does adjusting the focus have? +rep for DIY
So you can burn three things at once...wait..how did you LPM that thing?

That is just awesome!!! Great beam shots. That's one good looking beam. Good looking host, EP does some nice work . Nice, very :drool:

Yes, there is a lens. Also interested in seeing what it looks like focused to a point though.

As for LPM ... just hold it close to the sensor so all three beams fit I'd imagine. Never want to focus a beam onto an LPM sensor, otherwise you risk burning it.

I think I'll do that now

I am using a Sanwu G2. The initial focus looks like a regular unfocused multimode but as you tighten it the line slowly develops into 3 blobs and then into 3 distinct lines. Also, to lpm it, you gotta get suuuuper close it has a tight beam at first but expands exponentially towards the end.

Thanks!

Nice build Zach!

That is just to awesome a beam, I might have to consider getting one myself. Curious, with the tri-beams does it get hot quick ? What is the run time you can get ?

It is just like a regular red, but instead of 1 emission zone it has 3. It doesn't get hot very fast either. I am not sure where to get them anymore as I think Podo is currently out of ready supply.

Ok thanks, know that the red doesn't seem to get hot that quick, so I was wondering? I'll ask Podo and see what he said? Maybe he's got some idea where to get one . You got my appetite up with those beam shots!

Very beautiful pictures!!!

Is it possible to fix 2 small mirrors on the head to make 2 lateral beams knife-edged with the central one?

Or has anyone already tried it with this LD? Maybe in a non-portable?

Maybe a collimating lens close to the G2 would help?

Nice, the output looks exactly like that of my Sanwu tribeam.

It seems the batteries I was using were not providing enough current/voltage. I put 2 stronger ones in and got just under 1800mW Ill charge up the new ones and see what I get then

Been thinking about your build all night. Sent Podo a request for a diode, keeping my fingers crossed. Gotta get one.

I'm glad I inspired to to make one of your own


So does anyone know if there was a way to flip the lines/axis on these? I think it would be a much cooler looking beam and dot if it looked like 3 vertical lines instead of 3 horizontal lines
Like this:

(Ignore spaces in the middle of the lines)

Instead of this:
