Might be that lasers will start showing up on missiles. Hard sci-fi has its missiles carrying nuclear-pumped X-ray lasers, but I suppose smaller, non-nuclear versions could do well enough for terrestrial use.

As for "laser deflector shields", we haven't cracked the "deflector shield" part yet. The closest thing we have to force fields is actual matter - in this case, probably kicking up a dense dust cloud to scatter the laser.
