You can put it in a deployer, but it may only face down. The other single shot modes can face any direction besides up. However, only being able to shoot in 5 directions doesn't make for a particularly good weapon. And cycling lasers through a charging bench requires compact, expensive power sources like an mfsu and 2 hv solars (to make up for night cycles), and solars are easily blocked from the sun.

There's better choices for a turret. Tnt cannons (with CCSensors targetting system) have much more range, shooting mining turtles gets pinpoint accuracy and mines through any amount of reinforced stone you want, and a deployer with archangel's smite and klein star targets mobs and players automatically when shot. Laser turrets with their low range and almost no aiming capability are one of the worst weapons you can use in combat practically.
