Just to kick off this party, don't get a laser head for your desktop CNC. Just don't. Xenocrates wrote up a much better reason than I could possibly do, so here it is. Non-quoted so the whole thing ...

Anamorphic beam shaping optics are used to transform elliptical laser beams to a round shape - for example before coupling them to single mode optical fibers. Conversely, there are cases where ...

Fraunhofer ILT and Cailabs are entering a development partnership to advance wire-based laser material deposition for demanding industrial applications. Cailabs contributes a new, particularly compact ...

Investigating laser technologies in bioelectronics, this review highlights optical principles that optimize fabrication ...

However, it appears that they are owning that it's a class 4 laser, they've enclosed the machine for the most part and put in interlocks to make it safer, and are otherwise doing a reasonable job. I ...
