It can last up to 2000-5000 hours. Laser life is dependent upon operating methods and proper care. Running at full power repeatedly will greatly shorten the life of the laser due to thermal stress on the circuitry.
Keeping your laser below 80% power during normal operation has been shown to help prolong the life of the diode. We also suggest to our customers to take advantage of routine "cooldown" stages during long projects, as this will help prevent overheating.
As they are powerful electro-optical devices with a finite life span, laser modules should be considered as a type of "consumable" item requiring occasional replacement.
