Usually the adapter will list the polarity of the output wires. If it doesn't you can always try hooking it up both ways and see which one works.

wont it kill the laser if i hook it up wrong?
That depends on whether or not the laser has reverse polarity protection. If you don't want to risk it just hook the adapter up to a multimeter/LED/something else with polarity.

If you are referring to the dx 100mw red module it has a decent driver that probably has some form of reverse polarity protection.
