The pulse laser diode test system is an integrated synchronous test system for the early testing of laser diode manufacturing process flow , especially when the proper temperature control cannot be easily achieved . In a compact semi - frame instrument , the full source and measurement functions required for the laser diode pulse test and the continuous LIV ( light - current - voltage ) test are provided . The tight synchronization between the source and the measurement ensures higher measurement accuracy and can test the minimum pulse width of 500ns .
Main features and advantages Annex / Module applications:
