The +12 & GND on the laser are connected to the power supply.
It looks like this software is for a CNC machine with a motor-driven spindle. I guess you could use the motor on/off signal to turn your laser on/off, in which case you would connect the laser ttl+ to D10 and the the ttl1 to GND.
What wattage laser did you buy? Please post back how well it works.

Laser should be connected to 12V supply
from DZT 's Store website ---- PWM/TTL:support . TTL 0v off ,5v on
so supplying 5V to the TTL should trigger (turn ON) the laser
The TTL is modulated by a PWM signal from controller to get various power output
(longer pulse width --- more laser ON time)
What firmware and software are you using?
Many of SW programs allow selection of how laser is triggered.
