Keeping my 2.8W 532?

[CurtisOliver]

You will see a slight increase in brightness with the 532 due to it being closer to 555nm. But the main thing contributing to the brightness will be the beam specs. 2.8W of 532 in a handheld would be insane and a technical masterpiece.

Yea, it would, know anybody that might be up for the challenge ? :thinking:

If I had money, I sure would try!

Visit my new Gofundme page. Not really

I could afford it, if I could find someone skilled and trustworthy enough to commit to it. Thinking this is something beyond my skill set. So I'd pay someone else to build it for me? But sense we're talking a chuck of change, would have to done professionally.

Ps. Looked for your "go find me page" and couldn't fund it ???? . ( pun intended )

If you PBS combine two 1.4 watt output (1 watt rated) 520nm laser diodes you could probably have close to 2.5 watts in a pointer and wouldn't have the stability problems of trying to build a high power DPSS without all of the heat sink used in a labby.

Edit: I should add, the divergence of 520nm laser diodes are poor compared to DPSS, the beam would need to be expanded quite a bit to equal the divergence of a 532nm DPSS. I'd go for high power DPSS any day over laser diodes.

I already have a Rick Trent dual diode build, it has two 520's pbs'd together. I did a short review on it , it's putting out 2.8 watts. It's the one he did a video on on his you tube page. Having 2.8 of 532 would be something special, would have to be heat sinked correctly so it would be stable. Would make it quite large, so it's the size of a small baseball bat , think it might be doable :thinking:

Thinking of a 6 battery mag lite with a custom head/heat sink ???? Could use 32650's at say 4 volts each would give 24 volts to work with???

Oh, that was yours

I'd like to have a high power DPSS in something that size too, but I'd put a 3 inch diameter PCX lens on the end of it for uber low divergence

I don't know what is required to run most labbys, or this one. I'd make the supply voltage high enough so the voltage doesn't drop too far to run the laser too early, i.e., as an arbitrary example; if you needed each cell to be 3.8 VDC to produce enough voltage in series, the laser would stop working before the batteries are depleted much.

I'd need to know the current and voltage needed to give a better example or opinion. Last time I gave an opinion on batteries I was misunderstood due to the minimum voltage needed to run the green laser diode, then challenged and whipped with a wet noodle, so I'm going to be more cautious this time around and state a disclaimer; the voltage a Li-ion battery is depleted so far it should have a recharge can vary quite a bit by manufacture and model of battery, regardless of the size. Instead of using batteries like that, I'd look into using a Li-ion brick.

I appreciate your input ( I'm not the language police ) so any and all suggestion I heartily welcome. Still like to see if putting this in a handheld would be doable. :thinking:

I'm sure it's 'doable', but the question is whether anyone is skilled enough and has enough confidence to attempt it.

These are the main technical difficulties as I see it:
1-You would need to get rid of the mains powered driver and use a compatible battery powered driver. Might need to combine multiple lower powered drivers or build a custom driver to get enough power.
2-You would need a beefy power source, probably something like 2 26650 batteries.
3-You would need to remove the laser module from the big heatsinked head it's in without damaging anything.
4-You would need a custom host and heatsink for the module.
5-It would probably need TEC cooling for stability, and that adds even more complexity to a handheld build.

So basically you would need someone with comprehensive machining, mechanical, electrical and general laser skills to pull it off.

If somebody pulled all this off they'd have the bragging right of owning the most powerful handheld green laser in the world.

Or you can just stuff it all in a big fat round tube, add a 12 V to AC inverter and have the worlds heaviest hand held pointer too.

 

[ElectricPlasma]

Why make it smaller, keep it the same size, and make a big laser rifle. Or better yet, and more suiting, a laser "rocket launcher" :eg:

 

[Razako]

Yeah I guess one could go for the 'laser flamethrower' approach with a 12V battery, inverter and the power supply in a backpack.

 

[DashApple]

The internal driver uses 5V / 12V , you could just use a 12V battery and a buck for 5V , no need for the inverter and that , just extra weight that can be avoided

Know anybody up to the challenge?

 

[CurtisOliver]

I don't know anyone who would risk it with a laser that expensive. I certainly would prefer it in lab form anyway. Far better stability, heat management and no power limitations.

Thanks for all the thoughts and input. You'll never know unless you try. Because it's never been done is a reason to do it. All things might fail but that's not a reason to not try. :
