Default "beam board" tutorials, ideas?

One of them members has a neat setup with a blue laser (473nm I assume) here:

I was wondering if it was possible to do this with multiple lasers and "combine" the beams like in the 7 color laser build with something (a prism? sorry, noob here) and then split them back out or other cool things like that. I love the beam table idea, its like lego's with lasers!

If you want a visible beam like his blue in that photo would you want a nice tight focused lower power green? or a high powered laser? I ask because I'm assuming with a higher powered laser you'd want to wear goggles the whole time, even when your done setting it up which would block out the beam (right?) making the whole thing kind of a boring endeavor if you can't actually "see" the end product.

Hope i'm making sense here. Just trying to be safe, yet make some neat light art

Hi Ben!

Welcome to the forum!

Yes, as the link describes, the blue is 473nm.

I do have details regarding my optics mounts here: Mounts for optics
More laser pics and beam demos at my laser page here: Roosl's Lasers
I got the optics (a nice set of lenses, mirrors, prisms, etc.) here: Optotronics Laser Products

Now, Yes. You definitely want to wear your safety glasses during setup while a laser is on. Yes, the problem with these experiments is that you can't see what is going on if you're being as safe as possible. So, you also can't have a safe audience. Hence, unless you are taking pics or videos, you're left with the frustration that you are the only one who knows how friggin' cool it looks. If you peek. Yes, I peek (tho it makes me nervous).

I do plan to try combining beams via lens, prism in a future fun-filled afternoon, but right now I only have the blue and green. Shots of both in parallel is also on my list.


Again, welcome. There is a lot of other stuff to read about here.

Enjoy!
