Laser Weapon Operational

[Heywood]

I wonder how soon it would be before people start to install angle reflectors on their missiles so any laser beam pointed at the missile will be reflected back to the laser projectors and damage or destroy it.

The difference between a laser weapon and a projectile weapon is a target can reflect the laser straight back at the laser gun. No one had invented anything that can bounce a bullet straight back at the gun that fired it.

Mirrors do not reflect 100% of the energy so even if hit with a laser they would begin to heat and distort/discolor. Further mirrors only reflect a narrow range of wavelengths. If you want to destroy a mirrored surface with a laser, then fire a laser whose frequency is not reflected by the mirrored surface. A variable frequency laser would easily defeat the mirrored surface defense.
