Combining 5x 808nm

[Glenni]

So I have quite a dilemma, seeing how I'm "sort" of new to lasers. I've toyed around with them for a while, but I haven't done anything like this before.

I'm building a CNC machine, which I'm going to strap a laser on. I have a quantity of 5x 808nm lasers (Each of which has a power output of circa 1W).

Is there any way to combine theese beams, and get a decent focal point? (Decent as in 1-2mm, I suppose)

(Yes, I know that IR isn't the best laser for engraving / cutting, and it's still a WIP, I will most likely add a co2 laser in the future when I know I can count on it)

You could knife edge them, then use a lens to focus it onto the CNC table. What are you trying to do with this CNC machine?

5W doesn't go far with CNC, you may be better off saving yourself some time and just take the plunge with a CO2 Laser.

I know 5W doesn't go that far. I'm gonna use it for foam / engrawing wood.

That sick build, HOW DOES HE DO IT? Dude has got to be a wizard.

Just buying a 5W diode would likely be cheaper than buying all the equipment to combine what you have already, and the single die beam will be better than a knife edged array.
