      How does the RPT-LASER Works?
      The RPT-LASER laser diode testing includes burn-in testing to detect microscopic defects and ensure that high power diodes deliver stable optical output and consistent slope efficiency over time.

      During laser diode qualification, key factors such as output power, voltage drop, and near field performance are evaluated to ensure high power operation and reliability.

      Accelerated aging is a cost-effective method to test laser diodes, verifying their durability while maintaining optimal optical power and ensuring they are optically tested for maximum efficiency.

      How Does The LIV Test System Works?

      Semiconductor diodes are placed in an environmental chamber at a set temperature and current and is applied to the laser diodes  at interval steps (LIV test sweep) and the intensity of the resulting emitted light and voltage is measured. The final laser diode LIV test results are displayed onto a graph which is known as an “LIV curve”.  The following characterization can be determined based on the LIV measurement: Power vs. current ; Power vs. voltage ; Threshold current ; Series resistance ; Slope efficiency.

      Why Use Accelerated Lifetime Testing & Burn-in for Laser Diodes?

      With the rapid advancements in the electronics industry, reliability is a concern in every laser diode testing application. Laser diode life testing or accelerated aging is extremely important as part of qualification during product development as well as for batch testing throughout the production life of the laser.

      Also, high-temperature burn-in tests are used in laser diode manufacturing to filter out components prone to premature failure and ensure the remaining lot of laser diodes will meet the acceptable level of reliability based on the test standard used.

      How is Laser Diode Qualification Performed?
      Laser diode qualification involves rigorous testing to validate the diode's readiness for specific applications. Each diode is optically tested to ensure its optical output meets the required specifications without excessive degradation over time.

      Testing also ensures the diode delivers consistent output power under varying conditions. This qualification process is essential for achieving reliable laser performance while maintaining a low cost for high-volume production.

      What is the Importance of Laser Diode Testing?
      Laser diode testing is critical for ensuring the performance and reliability of a laser diode before it is integrated into an optical system. During testing, parameters such as optical power, optical output power, and voltage drop are measured to evaluate the diode's functionality.

      By analyzing the resulting LIV curve, engineers can assess key characteristics like slope efficiency, which indicates how efficiently the diode converts electrical input into light. Proper testing also helps identify any issues with the diode element, reducing the risk of failures like catastrophic optical damage that could compromise the system's performance.

      Burn-in testing is often conducted to simulate real-world conditions and confirm the mean time to failure, ensuring long-term reliability.

      Does your equipment work with unpackaged components?

      No, all semiconductors need to be packaged in order to mount them to the customer DUT (device under test) boards.
