I am a beginner!

Hi, recently i have been intrested in lazers and like modding stuff. I am on to lazers now and need some help. At the moment i am harvesting my own lazer out of a portable cd rom. I here most are ment to have only 2 wires but mine have 4. What i need is a really simple wiring design on how you remove all the other components to leave just the lazer and the 2 wires? Is there any resisters involved? HELP

Thanks a lot (sorry for spelling mistakes)

Please read the many tutorials found here. The search button will find treasure for you. You will also find that the word is LASER -- there is even info about what that means.
Good experimenting
