Theoretical Maximum Power for Portable Laser

You could get a small shoulder/belt bag with batteries, driver, pump, and water bottle.

The "pointer" itself would have a thin copper pipe integrated in the heat sink, the cables and tubes would lead back to the bag.
If you cut a large tread in the heat sink, plus a longitudinal groove, it can be wrapped in pipe* with both ends ending inside the handle for connections.

The only limiting factor now is the diodes available.

*e.g capillary tube from a thermostat, solder the whole thing for good contact.
 





or you could try running a 445 diode at 10A and see what happens. you might set a new record for a few seconds :D
 
Come to think of it, "Portable" is really the wrong term to use for this kind of question (as kindly demonstrated by sir Pullbangdead ;)). I do believe the term "Handheld" laser would be more appropriate.

Oh and HMike, is there a thread regarding that thing that you could possibly link me to? :thanks:

I agree with what some others have said, the term portable is vauge, maybe it should say handheld? Possibly "human mountable"?


@pullbangdead: LMAO :crackup:
 
I suppose that, with the size of 3 cigarette packs one near the other, and using LiPo batteries, a "combined" unit can be built ..... something like, 4 x 445nm diodes, coupled 2 to 2 with knife edge system, then combined with a PBS ..... and stressing them a bit for 1,5W each one, you can get 6W of 445nm that "almost" fit your pocket ..... :p :D

Guess it would eventually look like this...

Well, I described the simplest version, there would certainly be refinements during the design/construction.

BTW: UPS units tend to be powered by 12V 7,2Ah lead batteries, that would mean plenty cheap juice in a shoulder bag.
 
@pullbangdead: hahaha that's great!

And as for "handheld", does this flashlight still count?

:p :D
 
You could mount a Casio A140(cover removed) to your helmet(strapped to your head) and have a gas powered leaf blower motor charge the batteries in your backpack. ~24 watts, in an "extreme multimode" package. Just pull the hand held trigger and point your head in any direction as necessary. Make sure to do a lot of neck strengthening exercises before using it. ;-)

I love the proton pack (see also my avatar) and I still waiting that some expert builders will make a CO2 handheld laser with it :D

It's true but maybe the thread's author wanted to discuss only about continous wawes :thinking:
