Re: Laser Project

OK, Like I build one of those 55W CO2 Laser Kits (someone just posted
the web page, and I didn't bookmark). and like later on... Could I
add a second 55W Laser in parallel? And like a couple more next time?

I can't visualize any way of optically coupling two or more beems
exactly. One could get close by just hitting the same spot with as
small of a angle as possible.
If one could, would there be problems with mismatched coherence or
such of the mutiple beems?

By the way. These Kits look like a cinch for hard core machinists.

I had another thought. (no it wasn't gas)
Combining a CNC Lathe with Laser for shaping optics.
