11W blue laser "hell burner". Hello from Russia ;)

[ricktrent4]

that is good to know!

I think this is entirely plausible. I have cut a Tungsten filament inside a small incandescent bulb before with a focussed 450nm beam (~2.5W).

thin, darkened metal will absorb enough heat to melt.

:thinking:

Truly awesome ,not much else to say beyond way over overkill ,great job

Today I post the inside of my "Hell Burner" Enjoy watching , see below

Thanks man! :beer:

Pretty cool, how hard was it to align everything?

It was not difficult. The main thing is practice

Well sorry if I sound as complete combining noob, as I am. But those diodes are all in series ? That seems interesting to me .. just one driver ? What kind of driver ?

 

[The Lightning Stalker]

An LM338 would do it as long as the input voltage did not exceed the voltage drop of the diodes by more
than 32V. A 65V 3A power supply would power it all.

 

[superlazers]

One driver for all laser diodes, 32 volts, that's right

Maybe with 4 of your devices combined, you could do some engraving using a mask.

I would like to see the beam hit a fluorescent material. There should be some glow before it burns up.

If I have an order for 40 W blue laser, then I will shoot a video for you!
:lasergun: It should be a BLUE BEAM ))

If you send me a fluorescent material I'll take this video )

wow! and WOW! thanks for a peek at the insides. your work is very inspiring. i may have to give some beam combining a try myself.

 

[SerpantSlayer]

Very cool to see the internals! Must have taken you forever to align the optics for all those diodes!

Holy crap, that was absolutely beautiful. How much did it cost to make it?

Thanks for the tip! I spent about $ 900

I'm impressed, that's less than I had assumed. Does it need external lenses that you hold with your hand to focus the beam, or does it also have a focussing lens like "normal" lasers? And what kind of lens did you use when you cut that metal wire? It appears to bend the beam into a cone that curves inwards, which is something I had never seen.
