I'm too tired, must've missed that.. better go to sleep and check this thread again in the morning :P

Ok, help me out with the math. I may just be wrong in assumption, but I wonder if there wouldn't be some increase in final output with all 3 diodes? It would seem to me with an exponentially greater number of photons slamming into an object simultaneously, that the ultimate energy dissipated (watts) would be (slightly?) higher. Or, is it simply an additive number of additional photons with all 3 diodes? Doesn't seem intuitive though to expect total output in watts dissipated would be more than the sum of the diodes' possible, individual output. :thinking: My brain hurts..

Just remember conservation of energy. If individually they have a certain power, adding them together will not create new energy, it will merely combine the energies. Actually if anything were to change I would expect ever so slightly less power. But that is just me being cynical :p
 
I've need to buy my own mill and machine tiny mounts so I can adjust the optics., that would cut down on the time. I already have the lathe so I could make my own multi-diode hosts then too

Hi ARG, have you considered printing out the lens mounts in 3d. They're small and some of the metals aren't that expensive, not when compared to the cost of a multi-diode build. I'm still getting the hang of it. Just got notice that my part didn't print. Shapeways needs a wall thickness of .3 mm. That's not bad. I just screwed up because I am new to the program I'm using. There are a few very talented 3d modelers in the community and you are already familiar with the process I believe. Shapeways is cool in that you can design a part, print in cheap plastic to prototype and then print your final piece in the material of your choice. Than it's shipped right to you. Loooong lead times though. Not a good idea for a contract gig, but for your own project it might work.

Congratulations once again.

No idea, but my final rating of 6W+ would still be true then :p

I thought about that once, and forgot. Thanks for reminding me :) My printer does 100 micron layer height with a nozzle diameter of .35mm, I haven't had much luck printing small things, but with some calibration I think it should be doable.
I'm not great with CAD myself, but mhemling has done some amazing work with LPM cases.
Only thing I'm worried about is the rigidity of plastic, it may not hold the alignment as well as Al. Will have to take a look at shapeways and see what materials they offer, I could prototype on my printer then get them to make it in metal.

Thanks for the tip!
 
Just stumbled on this thread. Man what a nice build. Think I'm going to have to do some research so I can understand the tech better.
So, if I am understanding you correctly, you could combine 2 or 3 of the same diodes to get a more powerful mw? i.e. (3- 300mw 532nms) to get a 900mw. 532nm

You can combine two of the same wavelength, and or two different wavelengths.

For example, this build uses two 445nm and one 638nm. Since you can only combine the same once, you have to use a different wavelength to get three. He uses two methods of mixing.
So you couldn't mix 3 532nm, but you could mix two with another wavelength.

I wonder if two 532s would work with a 520....

Shapeways material comparison chart
I submitted my heatsink model to be printed in silver, gold plated bronze, bronze and stainless steel. the part is 9mm x 5mm Silver was 40+ stainless steel was about 10 something. Mhemling got a quote a while back for 300 for an amazing stainless steel host he designed. He's quite talented.

Thanks!

The answer to your question is yes, you can combine two or three of the same diodes to get more power, however you will loose some power in the optics so if you combine 3x 300mW 532nm you'll likely end up with 750mW.

Check out the tutorial in my signature for details about how to combine them. :)

Those prices are pretty good! These mounts are tiny so it wouldn't cost much. If it's under 30$/mount it's well worth it.

Just blew up my camera taking the pictures, let's hope they turned out okay :p
 
Yeah, all the photos are bad, sorry folks.

What happened was I turned on the flash, took the picture and instead of a flash sparks flew out from the flash area and it sounded like an electrolytic inside popped.
 
***must find old camera laying around house somewhere!!!!!***

or a cell phone works :p
