The idea of drawing with a laser sounds interesting. It reminded me of what
is now probably regarded as "stone age" technology, plasma arc cutting
using a projector. I started my drawing career as an apprentice draughtsman
way back in the 1950s when technical drawing was still done with tee square
and set square. In the shipyards an optical cutter was used. An acurate
scale drawing done on tracing paper was projected onto the steel plates set
out on the shop floor. A plasma arc cutter, (or oxyacetyline, but was less
accurate,) would travel across the plates and cut along the projected lines.
A lens in the top of the machine would pick up the projected image and
direct the machine to cut out the required shape.
Ancient technology perhaps but I thought it might make an interesting
footnote.
It sounds like lasers work in a similar way only on a much finer scale.
