Laser Diodes & Sources
The PUML series fiber-coupled laser diodes are FP-type lasers specifically designed for pumping doped fibers in EDFAs. These diodes deliver high output power and include a built-in photodiode for precise monitoring and feedback control of the laser’s output power. Encased in standard butterfly packages with TEC cooling, they are pigtailed to a 1-meter single-mode fiber terminated with an FC/APC connector. Each unit undergoes rigorous testing to ensure reliability and is available in both single-mode (SM) and polarization-maintaining (PM) fiber-coupled versions. Additionally, we offer a cost-effective, high-performance feedback control laser/TEC driver kit that maintains constant and adjustable output power, along with an externally cooled mounting fixture to stabilize the output wavelength. It is available in module or benchtop.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
988nm PUMP Laser: Laboratory optical integration depends on preserving the optical budget through the complete path. The 988nm, 976nm wavelength specification sets source and detector compatibility. The fiber/interface entry (Hi1060, PM980) must match the connected components.

Technical FAQ
Fiber Type: Hi1060, PM980 · Fiber Buffer: Bare, 900um Loose Tube. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 988nm, 976nm. Check the Laser Diodes & Sources passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
