Question: How do you build a laser experiment from scratch?

Mark Wallace answered on 8 Mar 2014:

It’s a lot like Lego to be honest, or even better Mechano if you’ve played with that. The laser I use is really similar to a laser pointer like your teacher might have. You screw the laser down onto a big metal table and then send the beam of light into a bunch of mirrors and lenses that sit in little mounts.

Check out the picture on my profile page to see what I mean.
