I had an interesting learning experience. I bought baltic birch plywood and it lasered really well. I then thought I would be smart and buy “marine grade” plywood so my outdoor pieces would last longer. Similar wood, but different glue holding the plies together. That stuff would not laser regardless of how many passes I used.
The moral of the story is that not only is it the material that makes up the laminate that is important, but also they type of adhesive holding the lamina together.
