Arduino using a button to switch on and off an IR laser

Hi folks, just needing some help with this code, I'm trying to make it so when I push the button and it counts up it will turn on the IR laser and will stay on until the button is pressed again where it will turn off and wait for the button to be pressed again. My issue is that I can get the IR laser to turn on fine and everything else with the button works but I can't figure out how to turn off the laser once its on. Any help would be greatly appreciated.
