New "Worlds most powerful handheld laser"?

[Cube777]

I was on eBay one day and this popped up: HERE. At 4.5A I does 5W Anyone with a LPM willing to try this? You could get the new "Worlds most powerful handheld laser"!! Imagine combining two of then to get 10W!!!!:eg:

Well that thing would want a massive heatsink...
It could be used in mini CNC Cutters :beer:

I think if you used this diode your going to something like a SIAK host!

 

[Moistenator]

Imagine using that in a DPSS conversion to make 532

 

[Cube777]

If you can get your hands on some very efficient crystals this can be one hell of a 532nm laser. Imagine having a 2W 532nm laser

lol, if you could call the output of that a laser. More like a flashlight.

 

[Cube777]

Do you guys think this will be up to spec?

 

[Fiddy]

Its 808nm so invisible to human eye, super bad beam specs. I did a 3W 808nm Saik handheld a while ago but couldn't get 3W's out of it, think the amc-drivers couldn't handle it.

 

[Cube777]

I think for the driver you will have to use a linear driver like a LM338, they can handle 5 amps.

 

[Things]

Why would you want to build anything with this? It's pretty much useless as far as a laser goes. Like I said, it's divergence will be horrible. Wouldn't doubt a dot over 30cm at even 2 metres

Not to mention it would be invisible?

Comment on the 532nm: Even if this diode hit 5W as spec and you had an insane crystal that could handle it, I doubt you could cap 1.5W of 532nm. Good luck on finding a crystal for that lol.

Either way, this would be one hell of a dangerous and near useless laser. Fry your eyes instantly and you can't even see it... totally worth it.

We have a few of those 5W TO-3 Lasers in the shop.

If you want to build a handheld Laser with one of those
you can get the same 5Watt Laser in a C-Mount package.

These are Multimode Lasers and to get a half decent
beam profile you will need a FAC lens on the Laser.
It would give you a close to square beam after collimation.

I'm definitely not going to buy one of these, I was just letting you know about it!

I can dream can't I? :san:

Maybe the "Worldn's Most Powerful Handheld" title should now be limited to visible lasers only?

I mean idk, but to me, a laser where the beam is not visible, just isn't that much fun.

Besides, one could argue that the the lasers made by guys like Hemlock Mike (the laser rifle) and Anselmo... would also fall into this category.

Edit: A 2W+ green handheld with good beam specs, would be incredible to see. Most I've seen so far is 1.1W, and it's pretty impressive, but due to the crappy beam... not that much more interesting vs ~400mW.

I'm always weary about eBay lasers, too many under spec diodes from these mass-production laser companies.
