You may have a couple of problems, I would not think the amount of power from a 15 watt laser is one of them.

Your laser is probably not focused. The beam that comes out is a cone shape and can be adjusted by either raising or lowering the work piece or adjusting the focus ring one the aperture. It needs to be adjusted to the smallest possible beam size on your work piece.

You could also be running your machine feed rate too slowly. Speed it up an try again.

I regularly cut paper with a 100 watt machine by winding the speed up, it doesn't catch on fire unless it is out of focus.
