To be clear, that refers to a demo system unrelated to Starlink. I don't think it is known where the Starlink lasers come from or what their capabilities are.
All I know about them is that a reason they weren't deployed in the first batches of satellites is their original design included parts that did not burn up completely on reentry, and SpaceX wants Starlink satellites to always burn up completely, since there are thousands of them.
