    If I remember right the Hardinge HLV-H's we had at work had some sort of white plastic that the increments were engraved in and then filled with black paint.

    I have some of those lacquer sticks for markings. They work pretty well.

      I could be wrong, but I suspect the optics (lenses or mirrors) to go along with that diode array would cost more than the array itself. All of that light output must be focused on a single spot - or at least a large percentage of it. That is not a trivial task.

      You could do this with blue laser diodes too if you had a big enough diode array. But that would be one BIG array. I have cut copper with a green DPSS laser.

      And if you look REAL close at an analog signal,
      You will find that it has discrete steps.

        Thats what the direct diode laser systems on the market do, arrays of diodes focus through a transform lens, through a dispersive optic and out an output coupler. They are doing it with IR but there is no reason you can do it with other wavelengths,.

          I have a 30W fiber laser! Great tool for deep engraving and etching but unless you have a need for one on a regular bases they can be an expensive dust collector 😆
