The laser chisel is a hand-held tool, connected
fibreoptically to a very hefty CO2 laser. Within the body
the chisel, the beam is first broadened before emerging
from a cylindrical lens with its axis at 90° to the length
The lens arrangement ensures that a line of intense
light is formed a couple of millimetres in front of the
Beyond this distance, the light diverges again, becoming
relatively harmless a few centimetres away from the
The laser chisel brings to bear all the traditional skills of
sculpting, but can be applied to metals, plastics, stone,
wood - indeed anything that can be vaporised.

||Yes, well. What this idea lacks is an opening rant about the loss of craftsmanship in the maker generation.
||You would want to use a fibre laser, not a glass tube. I think handheld fibreoptic lasers do exist, used in some (retinal?) surgeries.
||In order to reach cutting intensity, you're almost definitely
going to have to go with a point, not a line. The way to turn
this into a chisel would be to scan this line across the width
of the chisel at an appropriate cutting speed. (Combined
