Is a laser module reqired to make a laser cutter?
I pulled a laser diode out of my 16x dvd burner drive and want to use it to make a laser cutter/burner. I want to know is it required to use a laser module or can I just hook it up straight to a battery and have it work.? Also how many battery do I need to make it work.? I tried hooking it up straight to a 9v battery but nothing happened.
