Turret time! Don't stand in front of them for too long, or they'll shoot you silly. Pick up and drop the first turret from behind.

Next part involves using portals to drop objects on top of turrets to knock them over. Do this for the two in the hallway and progress onto the three by the exit door. If you're out of cubes to drop, using dead turrets also works.
