Can you say something about what N-D lasers are and why they present such a strong threat? A google search for “N-D laser” just turns up neodymium lasers and it isn’t clear why they would be as threatening as you present. In the worst case, you build a probe with a very powerful fusion energy source which is able to fire a laser at people sufficiently powerful to kill them, you could probably also build a laser or defense system to strike and kill the probe before existential loss has been caused.
N-dimensional is just referring to an arbitrarily powerful laser, potentially beyond our current understanding of physics. These lasers might be so powerful they could travel vast distances through interstellar space and destroy a star system. They would travel at the speed of light so it’d be impossible to see them coming. Kurzgesagt made a great video on this:

I’m borrowing the term “N-D lasers” from Charlie Stross in this post: https://www.antipope.org/charlie/blog-static/2015/04/on-the-great-filter-existentia.html
