Positive and negative terminals of red laser diode
• Diode anode: Positive terminal; internally connected to the P-type semiconductor region; it is the entry point for current into the diode. How Does a Diode. The laser diode has usually three terminals: laser diode cathode (LDC), common (+) and photodiode anode (PDA). The common (+) is connected to the positive terminal of the voltage. Laser diodes, even without collimation optics can generate enough light to damage your eyes, and the ones you find in a lot of electronics are either infra-red or very deep red that is barely visible. This means they can be generating damaging light without you realizing it.
