i think some diodes have + and - on the outside, and the middle pin is like the gate on a transistor

If you don't know where it's from, it could be shining in invisible IR. Be careful not to point it anywhere near anybody's eyes.

Try to google the datasheet for the laser diode. The datasheet will give you the diagram and a description of all pins.
