Unlike bare laser diodes, the output from a fiber coupled diode is round and so it is easy to focus to a beam or a small spot using a simple lens. These are new and I cleave the end of the fiber and test each one before shipping.  Laser diodes are very sensitive to static so you must be careful to use ESD precautions while handling them.  If you leave the shorting jumper on when the diode is not in use and wear a static wrist strap while handling the diode, you should be OK.  You should also use a clean power source to power the diode.  A pair of D size batteries and a current limiting resistor works well.  I include a 0.39 ohm 2W resistor which will run the diode at a little under a watt with fresh batteries.  Note that the pin closest to the heat sink is the anode (positive) connection and the top pin is ground. Laser diodes are also adversely affected by heat.  These may be run for a short time with just the built-in heat sink, but if you plan to run it for more than a minute at a time, it should be attached to a larger heat sink.  An old CPU heat sink works great.
