How high-power lasers to test bench for 10 simultaneous samples burn-in works.
In this success case, we present two different challenges we had to face to meet the requirements of power laser users:
High power lasers (30watts in this case) require specific test setups and important safety considerations to avoid dangerous situations happening in DUT/setup failure.
Testing many lasers increases the difficulty and introduces additional considerations like heat handling or avoiding a laser to damage another.
Several failure modes exist for a powerful laser. Each one implicates safety issues for the operator and remaining samples tested but can be controlled implementing proper monitoring and safety countermeasures: fiber failure, overheating, voltage drop instabilities.
