Pulse Laser Diode Tester

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 one or several user-programmed test scenarios. Tektronix designs and manufactures test and measurement solutions to break through the walls of complexity, and accelerate global innovation. Another fundamental method is L–I–V characterization, where the optical output power (L) and voltage (V) are measured against the drive current (I) to determine key parameters like threshold current and slope efficiency. Furthermore, the article covers the analysis of the optical spectrum, the. The Model 2520 Pulsed Laser Diode Test System is an integrated, synchronized system for testing laser diodes early in the manufacturing process, when proper temperature control cannot be easily achieved. These instruments perform complete LIV measurements in extremely short time for high throughput by using pulse testing method, QCW and. However, several sources of error remain when pulse testing high power laser diodes, including problems with coupling high current pulses to the DUT, optical detector coupling, and both slow response and inaccuracy in the detector itself.
