On average, they last 10,000 to 50,000 hours under normal conditions, though some can exceed 100,000 hours with proper care. Honestly, it depends on several factors, and there is no simple chart to cover everything. Though, there are lifetime ratings outside this range, depending on the configuration. Furthermore, there are a wide range of degradation. When packaging a diode laser, choosing the appropriate solder preform for the die-bonding process is the critical first step for ensuring long term reliability, since the solder joint serves as the primary thermal conductor for heat dissipation. As a result, soft solders such as InSn are generally. If you're looking for a single, magic number for how long a diode laser lasts, I've got bad news: you won't find it here. Key factors like operating temperature, current, and cooling play a. Typical lifetime of laser diode modules are 10,000 to 25,000 hours.
