Touch the red probe (positive) to the suspected anode and the black probe (negative) to the cathode. If reversed, the reading will show "OL" (open loop), indicating reverse bias. As a bipolar component, a diode has an anode and a cathode at its two terminals, just like the positive and negative terminals in a circuit power source. How to Determine If a Diode is Forward or Reverse Biased? Can You Test Polarity with a Multimeter? What is Diode Polarity? Diode polarity refers to the direction in which a diode allows electrical current to flow. If it produces light, you were right, if it produces smoke, you were wrong :) Im 50% sure the left is negative.

Below are the key technical details of a typical Laser Diode Module: The Laser Diode Module typically has three pins or wires for connection: Note: Some modules may only have two wires (VCC and GND) without TTL functionality. My questions are very basic, but since it's the first time I will operate a diode like this, could someone tell me what voltage i have to apply to which pins? EDIT: I don't have a datasheet, or even an online reference. What should I do? From a bit of Googling it seems likely that the device has two lasers (probably IR and Red) and the usual photodiode to allow the drive circuitry to. ROHM refers to the pins of a three-pin package as pins 1, 2 and 3, clockwise when viewed from the top of the package (the side where the laser beam is emitted). I've seen other posts where people want to upgrade their 5w unit and depending on the laser driver/power supply they need an adapter board- but from my limited understanding that's just so the driver would. 3 pin diodes: Most of the laser diodes are 3 pin, most of the wavelengths and output powers have 3 pins leads.
