A laser question

[Ailenlube]

hi, ive been wondering somthing but im not sure on it, maybe you guys can answer my question

heres my question

if i get 10 high powered laser pointers, shine them into a mirrior and fuse all the beams into 1 laser, would that incrase the power of the 10 lasers into a really powerful one? Thanks!

Sure you can.

But its not as easy as you think.

LINKS BELOW-they realy need to make the links a different color.
Another project red?

I tried but failed! (1watt red)

Fiber Coupling Kit

Axicons to combine diodes for a single beam.



Goodluck

its hard enough making the beams for a scanner to align right let alone that many that is an amazing image.

How about this.....

those are 640 and 445 diodes (not the cheap ones)

I never get tired of looking at those arrays, just stunning

I think that picture of the Arctos unit is my favorite laser picture ever.

It's apparent they're not using the 1W 445's. then they wouldn't need so many.

Though I have to say.. shouldn't he be wearing goggles?

I think the majority of the laser diodes on the right are 405nm

If you shine 10 lasers in the same place, I'm pretty sure that the power won't always equal the added power of all the lasers. Destructive interference and all that.

Uhm, let me try to imagine (cause i don't have your setup in hands, so i can just imagine ) ..... probably your is a geometry problem ..... let me know if i'm wrong .....

For this is called "knife edge" combining

That 1 watt red is a link to another members build, not mine. I'm working on a quad now but its not the "typical" quad, its a 4 banger, doesn't use a PBS cube.

Nope, no cheap 405 in that bad boy, All (direct from nicha) 447 (aka 445). but that pic does make it look like 405. If you trace the beampath you can see what I mean.

Nice!! So if i do this i be doubling the power of the laser? Like a lets say 1W laser becomes a powerful 10W laser?

If you do it PERFECTLY you will have MINIMAL losses, But there will always be losses.

Now that was one expensive projector!

I cant even imagine/don't want to know. :shhh:
