Case Study
The successful performance of our laser diode reliability test system, which facilitated the analysis of 256 laser diodes to meet stringent design criteria, has earned high praise from the customer.
Quality assurance and reliability : Diodes
After the diodes are assembled, we ensure the quality of all products by conducting multiple measurements at a high degree of precision. Fig. 1 shows our system for quality assurance.
Pulse Testing of Laser Diodes
Testing a laser diode properly requires a current pulse of the right shape. It should reach full current fairly quickly (but not so fast that it causes overshoot and ringing), then stay flat long enough to
