Largest Wattage in Handheld Portable Laser?

i thought for handheld the scorpius d pro 3000mw ir laser would be the stongest unless you build your own

I believe that is the highest power commercial handheld laser out there. You could build your own laser with a high power ir laser.
 
I think he was asking about the 10W 532.. which I would have to guess no. lol I believe the video said the whole thing weighed 38lbs.
 
No DrSid neither are handhelds but they answered the question above as was stated: "Are there any videos of what a >5 W laser can do?"

If that was a 5W laser, they had some serious filtering on the camera.. 5W of 532 shining on a white surface like that would be impossible to be in the room with without eye protection and would definitely overload a cmos or ccd camera. Plus at 5W unless that was a piece of metal, it should be scorching it fairly easily. ... Not to mention it's awfully quiet.. Every high power green i've seen has had loads of active cooling (big loud fans)

because of that, the user blocked comment adding on the video :P (it is/was on ebay).
 
I think the day of someone using optics to combine 2 maybe 3 1w 445nm's isnt far away and in theory is "do'able" , the host would be big, but would certainly qualify as "portable".
 
You could combine two with a PBS in a large flashlight host.. I don't see anyone doing more than that though, since it would involve a LOT more complexity.
 
I believe that we should first clearly define the meaning of "handheld"...
 
For simple combining why not just tape 3 (or 10) same pen hosts together ? Sure you wont get one beam .. at least not at the aperture. And for burning you will just tape them around cone, so the are focused to one point.

Well handheld could technically be like this....

And as for multiple beams, you could use 12 white fusion kits with all 1W 445's so 3 kits put the 3W beams into another dichro for 9W :eg:. that would be almost like a half circle.
Thats just an example and if you could get the right alignment without the kit, you could just put 9 beams into 1 dichro.

You two both need to do a bit more reading about how monochromatic light interacts with itself. Neither method is valid due to destructive interference. Also, dichro's only work to combine DIFFERENT wavelengths.

There are really only two ways to combine the same wavelength together, and one of them isn't really combining them..

The first method is to use a polarized beam splitter to combine two 90 degree polarization offset beams into a single one.. This can only be done with two beams.. and once. If the resulting beam is run through another PBS, it will get split back into the two different beams again.

The second method is knife edging, which isn't really combining beams at all. It's just arranging the beams so they're parallel and aligned really close to each other without overlapping. If they overlap then you deal with power loss due to destructive interference.

The two methods can be combined though, You can have two knife edged banks, with one polarized at 90 degrees to the other, then run the output of each bank through a PBS.. but this arrangement with neither be remotely small in any way, or be robust enough to be swung or banged around and have any hope of all the optics and mirrors staying in alignment.

We'll probably see two diodes combined with a PBS in a handheld in the near future.. but I think anything beyond that is very unlikely.
 
Its not 100% complete annihilation of the wavelegths right? Because when I point two lower powered lasers at a match neither of them can light sometimes its enough to light it!

Not it's not complete, but the losses are a lot more than you get by doing it right. And in general, people don't combine same wavelength beams just to 'burn crap'. It's generally done for projector use.
