Laser Diode Controller and Mount Selection Guide

For Flexibility and Precision Control, Choose Newport Laser Diode Control Instrumentation

How do you select the proper Laser Diode Driver or Laser Diode Mount when you don’t know which laser diode will be best for you application, or you need to control several different lasers with unique operating settings? The flexibility of Newport's laser diode control solutions make them the best bet!

Selecting a Laser Diode Driver or Laser Diode Mount

Click Laser Diode Controllers and Mounts to shop or browse all of our standard models, or select a product series below for more information. Start with the laser or the LED that meets your requirements. Estimate the operating current, forward voltage, and the amount of heat generated at operating conditions. Choose the laser diode mount that can accommodate the package mechanically and thermally. Then select a laser diode driver that can supply at least 10 – 20 % more voltage and current than required. As laser diodes age, they will need more current to generate the same amount of light. Likewise, give some room for extra heat load when you choose the temperature controller. Keep an eye on the noise specifications, as they tend to increase as the output capacities of the instruments increase.
