laser diode being line instead of a dot

Ortur Laser Master - Laser not focusing to a dot

Well, it’s true that the output of a laser diode is elongated somewhat and not perfectly round, but what you are showing there is really awful. Ask them why everyone else’s diode lasers provide an acceptable beam shape but theirs don’t…

How small can you make a diode laser spot?

They aren’t wrong - high power diodes use a linear array of emitters, so they do produce a rectangular output though the highest power density is usually a small spot in the middle. It’s possible to use some special optics to shape the rectangular beam into more of a square, but that’s expensive.
