A few depictions of laser beams in use from the popular press of the late 1930s to early '50s. No wonder green laser pointers got such a bad rep. The public was warned!
Man it's a good thing that lasers didn't exist in the age of hydrogen filled Zeppelins. It's bad enough these days with idiots pointing them at planes.

The problem with hydrogen filled Zeppelins was the Germans didn't have access to He and it only took a spark to ignite the hydrogen in in the presence of oxygen. Funny story.... the Baroness Von Zeppelin was happy that Jimmy Page had decided to use it as his band's name until she saw the cover photo of their first album.
