Basically you generate a self-contained gravity envelope -- handwave, handwave -- which travels with the laser beam and keeps it focused over enormous distances.

Maybe the generator somehow treats the local natural gravity as a solid medium, within which it induces a standing wave? Using the laser beam as it's guide path?
