What it does when used depends on it's "count" (can be set by a lua-script)

none
-----KEYS-----
count:
0 (default) - Fire in direction facing
1 turn left
2 turn right
3 aim up
4 aim down
speed - How fast it turns (degrees per second, default 30)
dmg - How much damage the laser does 10 times a second (default 5 = 50 points per second)
wait - How long the beam lasts, in seconds (default is 3)
targetname - to use it
target - What thing for it to be pointing at to start with
"startRGBA" - laser color, Red Green Blue Alpha, range 0 to 1 (default 1.0 0.85 0.15 0.75 = Yellow-Orange)
