Estimating Laser Diode Lifetimes and Activation Energy

Since laser diode lifetimes can be into the 100,000 hour range it is generally not practical to test the laser diodes at normal operating ranges due to the long test time.

What determines the lifetime of a laser module?

Typical lifetime of laser diode modules are 25,000 to 50,000 hours. If the laser diode temperature rises beyond the maximum operating temperature the long-term performance may degrade significantly,
