Laser Weapon Operational

[Anomalocaris]

It is trivially easy to change the frequency of a laser beam. Simply move the beam emitter forward or backward while the beam is emitted. Its is called the doppler effect.

Have you calculated what velocity you would need to move the emitters forwards and backwards to effect the perceived frequency of the beam at the target sufficiently to move it out of the band of a generally reflective surface using Doppler effect ?

Hint: Thousands to tens of thousands of kilometers per second.

Basically what it boils down to is this. Laser weapons make it easier to kill enemies.

Laser weapons also make it easier for moderately technologically sophisticated enemies to not only prevent your weapons from taking effect on their equipment, but also to use your own weapons against you.
