Remember that one end of the missle is *already* on fire and designed to
withstand some serious heat for at least a few seconds - and the other end
is being cooled by some really serious airflow.  And keep in mind that many
of the explosive payloads are going to be hard to trigger by mere heating,
they often need a detonator cap (probably buried *well* inside where it's
hard to hit) or electrical discharge or similar.

This setup is based on the Tactical High-Energy Laser, which was able
to take out salvoes of mortar shells in mid-flight, as well as
Katyusha rockets and MANPADS missiles.  It is a very powerful laser,
relatively quick to acquire and shoot.  It can be set for various
profiles, so that it will shoot at a target moving outside of those
parameters but not the Cessna coming in at 80 knots.

The laser is probably intended to detonate the fuel by hitting close
to the middle, or else cause structural failure due to weakening of a
part of the target, causing it to tumble and possibly explode on its
own.  I don't believe it takes long to do so, though I was not able to
find any information on the lasing time per target, something I
suspect is highly classified.
