Your laser would be switched on/off using a TTL signal (5volts or 3.3volts) not sure why you would want to use a relay.
Modifying your Vectric post-processor to replace any Z axis movements with a small A axis movement would seem the easiest way to use the A axis direction signal as the laser trigger.
