Is it possible to make a laser pointer with these items?

I have a small lens and some batteries. I have an old lenovo windows 7 laptop with a dvd player. I could take out the laser diode from there. So is there any other parts of a laser pointer that i might need other than the diode, lens, and fuel supply?

You'll also need duct tape

I don't think the laser diode in a CD player is visible light - better check that out before tearing it apart - should be how to build on Internet
