 (*_*)

below this text there is an image diagram, it should give you information you need,
 regarding size and polarity of this diode.

                                                                                        Reverse polarity, excessive current, high heat will damage these.

                                                                                        Constant current laser diode driver is required to drive the diode,

                                                                                        Never connect directly to a battery!

                                                                          Recommended current is 3v-5v @ 1 to 1.6 Amps. MAX

The diodes must be inserted in to a laser diode module with heat-sink
before energizing to dissipate heat.A glass lens should also be used.
 (lens is supplied in the sealed packet along the diode)

 !WARNING!

(below warning taken out from online forum article that was originally written by Dan Mills)

""Now a word about safety: 2W of laser is class 4 (in the old money) which means that both
 specular and diffuse reflections from surfaces are hazardous to vision (Never mind the direct beam).
 Bolt the thing down to an optical bench, and use appropriate ANSI certified eye safety gear 
(and shielding with interlocks so that a stray beam cannot blind anyone ELSE)
 and you are all good, but please, nearly nobody needs a handheld class 4 laser.
 Gear at this power is NOT a toy, no matter what some seem to think.""
