3.5W 445nm Worlds Most Powerful HandHeld Laser

This is a dual diode array based laser.. Features 2 x A-140 Laser Diodes, 2x aspheric glass collimating lenses and cylindrical optics for beam correction.
The beam emitted in the video is not focused down and is the parallel output
demonstrating the heat generated by igniting various pyrotechnic compounds.

OMG, Thats a REAL Beauty, Beautiful host, key lock, emission indicator and power button, this is just the most amazing Blue Laser I have ever Seen!

Whats is the diode rated? From in my knowledge a direct diode 445nm can output 2.5W.

LPM test would be nice and how many amps did you push this to? The lifetime doesnt seem it can be that long.

Great Video!

@LivingLaser47

Its 2 diodes, not one. They are combined outputs into a single beam.. Each diode is getting between 1.5.- 1.6A and are current regulated.

[LivingLaser47]

@TunedCavityLasers I barely realized after I posted that it is a 2 array diode A-140 445nm direct diode combined laser.

Even better. What does that BEAST run on?

@LivingLaser47

This one was 2 x 18350's @ 7.2v (avg) with a 2.8A draw on the cells. Separate drivers, both buck current regulators, one per diode.

The output is also passed through cylindrical optics to correct shape and divergence.

The LPM test you mentioned.. I can only meter 1 diode at a time with my current meter. I have a 10W LPM with data logging coming soon, and will then be able to add the graphs of higher output laser into the videos..

@TunedCavityLasers Cool, in that method are their RGB or RGV lasers using 3 different wavelengthed diodes together? I thank you for helping Styropyro out with the CNI 473nm lab module, I bought it and hope to get it sometime tomorrow maybe.

Also do you know any good multiwavelength LPMs that can read 1-2W and priced under $200? The radiant alpha is my main choice but its been out of stock for so long and the new batch wont be till after Christmas.

Thanks!

[TunedCavityLasers]

@LivingLaser47 Im actually working on an RGV now, other than mine, I dont expect to see many out there. My concept is completely adjustable to whatever colors you want

by adjusting slide controls on the laser.

For LPM's, I have had an alpha, was not impressed.. If you want a good meter, opt for a laserbee I or the like. Faster response and a proven product. Been using LB meters for about 4 years now, best bang for the buck.

Dat sum freaking power! Also, styro brought me here ;)

[styropyro]

This is the best handheld build from a hobbyist that I have seen yet. Absolutely incredible. Great video!

zooo my goodenes

[AnselmoFanZero]

You could say, I hate pointers, but this one rocks!

[tonylunnie]

I want to buy one of these and do u have a maintance kit and interchangable diodes and i like to buy one ot these. U make and sell them. I want one. Please get baack with me.

Thanks

I. WANT. ONE.

[ranamuhammadatif]

The man with the golden gun!

[giog1313]

how much did it cost u to make do u want to make sum money..

[giog1313]

can i get one!!!!!!!!!!!!!!!!!!!!!

[USAshOOTER]

Congrats, thats awesome.

[orion198606]

Wonderful! You can use this laser to kill some mosquitoes! Just one flash can kill them I think.

[TensaZangetsu86]

how much did i cost u to make it and where did u learn to make them i cant find a decent tutorial anywhere i would love to build 1 like that but no clue how to
