Reliability test system for laser diode qualification in pulsed or CW regime

laser diode reliability test system

Life-test and qualification test system for laser diode reliability evaluation in CW or pulsed regime down to 1 nanosecond. Up to 112 fully independent fibered devices are electrically, thermally and optically tested according to several user-programmed test scenario.

This laser diode reliability test system has been specially designed for the qualification and test  of  fiber-coupled devices with maximum of internal and external measurement flexibility. The laser diode optical power is measured independently from the BFMs or some external photodiodes with variable gain for a better precision. It allows for the independent and precise adjustment of the temperature of each laser diode package and each laser diode chip.
