You should be able to, but if it is only a dvd reader you won't get much output.... maybe 5-10mW, and it won't burn anything exept your retina. A dvd burners' diode would be better, and you could cut black tape and light matches.
You would be better off just forgetting those optics and stuff that you posted about, and go buy a dilda from DX. It would be less than $40.00 and it is already built for you.
