And all the laser has to do is blind the seeker long enough for it to lose

You could have a filter that optionally goes over the seeker. When a
laser is turned on, the missile uses its "sunglasses"; the power of
the laser is such that the missile can use it to seek the aircraft.
When the laser is switched off, the missile takes its sunglasses off
and guides towards the aircraft in the usual way.

This assumes that the filter can go over the seeker quickly enough
that the laser can't damage it, of course.
