If you are flying with stealth you may want to close off the canopy if
you can, if you are being searched out by lasers then your eyes could be
hurt before the systems and sensors would be hurt, in such a
progression. Think back on the problems with laser designators and the
various intentional and accidental bindings of personnel - this resulted
in laser glasses that were to protect the eyes in certain known utility
frequencies - but now the power is up and the spectrum expanded. The
aluminum canopy could actually be a glass/plastic one that when a strong
laser touches it turns immediately opaque and the helmet system becomes
the primary flight reference instrument set.

This is practical now; B-1B's use electro-optical material in the
windscreen to turn it opaque in a split second if a nuclear flash is
detected (I assume the B-2 has the same feature) to prevent the crew
from being blinded. The same technique could be used for laser attack
protection. More than lasers, microwave weapons might be the major
threat in the future.
