In that case it didn’t form a black hole until it interacted with the atom, and at that moment it slowed down from light speed. How do I know?
Until the atom came along, you’re free to use any old reference frame without complicating matters terribly. So you can arbitrarily red-shift that laser pulse to the point that the energy density is trivial.
If you do that, you shift energy into the atom. So, it’s the collision that allows it to condense into a black hole.
It is rather interesting question, what happens when the pure light black hole interacts with an atom. I have no idea, except that is interesting to consider this kind of questions. What happens under some peculiar circumstances. Do the current theories work there or break down?
As I mentioned before, there is no such thing as a “pure light black hole”. All uncharged black holes are pure vacuum, regardless of how they formed. There are also no beam-shaped black holes (all black holes are spherical in shape, this is a well known result in General Relativity), though a regular black hole can theoretically form from light alone (kugelblitz) under certain rare circumstances.
Your model has a number of technical errors which prevent it from working. For example, you cannot form a black hole by shooting a light pulse from a laser, except maybe by focusing it, in which case the center-of-mass velocity will be sublight and you end up either creating multiple black holes or feeding a single one, depending on the details. Moreover, while light does curve spacetime, it’s not as simple as the gravitational attraction between massive bodies. There are many known solutions which include perfect null fluid (that’s what a continuous beam of light is), none are trivial.
If you still think that you can think up something that 100 years of GR research by the geniuses like Einstein, Hawking and others did not notice, consider learning the subject seriously first.

I don’t know the answer, who does?

I haven’t invented a thing in General Relativity, black holes and so on. I have no intention.
