The Function of the Unused Pin in a Laser Diode
The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively.

How to determine the positive and negative terminals of a laser diode
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.

What causes laser diode light decay
Thermal strain, laser radiation self- absorption, local collapse of the thermal conductivity, and thermal lensing are the mechanisms inducing the defect formation and propagation leading to the device failure. Among the limitations known from semiconductor lasers, catastrophic optical damage (COD) is perhaps the most spectacular power-limiting mechanism. Here, absorption and temperature build up in a positive feedback loop that eventually leads to material destruction. Semiconductor laser diodes are important components for various applications such as 5G wireless, datacenter, passive optical network, and aerospace applications. High reliability has emerged to be the universal requirement for all optical applications.
