Ouch...
CD=IR diode...
IR=non visible/VERY faint red light
CD player=<5mW...
You should have used an CD writer if anything...
Sorry to be the bringer of bad news...But your diode is pretty much useless... :-/
Try to get a DVD Writer next time...or buy one of senkats diodes...

Sure,anytime *
btw: http://stonetek.org/shop/
has everything youl need to build a high power red...though i would recommend playing a little w/ cheap 1-5mW laser just to get the idea...(not necessary,but recommendable to learn how everything reacts to it...though this is personal prefference)...make sure all your comrades are aware that they can blind themselves & others easily w/ your greenie...and have them stand in awe while you point it at the stars and...boom a massive shining beam of beautifully green light * seemingly endless into the stars

As I recall, the 16x diodes will output about 150 to 170 mW at 250 mA of drive. Heatsink required.
