What Determines The Service Life Of The Laser Module?

Laser Module

TEC DIODE using 100% pure AUSN laser stack from US Coherent. ensure 20 million shots super long lifespan.


The typical lifetime of a laser diode module is 25,000 to 50,000 hours. If the temperature of the laser diode rises above the maximum operating temperature, long-term performance may be significantly reduced up to and including complete failure. With a decrease in the operating temperature of the laser diode by about 10 degrees, the service life is statistically doubled.

Keeping the case temperature at the lower end of the operating temperature range can significantly extend the life of the laser module. Heat dissipation recommended. If the laser is running all the time, you need to use a heat sink. Operating the laser module at the lower end of the recommended voltage range can also help extend the life of the laser.
