Laser Diode Light Efficiency
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.

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.

Laser diode three-pin or four-pin
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.
