Laser Diodes & Sources
The FCNL series of Fiber Coupled Narrowline Laser Sources delivers linewidths as narrow as 3kHz and output power up to 200mW in single-mode or polarization-maintaining fiber. Each benchtop laser source features high-precision, low-noise auto-feedback drive electronics to ensure constant output power or constant driving current. An integrated temperature control unit maintains optimal operating conditions, and a built-in isolator prevents reflection-induced laser instability. Each unit includes a front fiber output connector and a universal power supply compatible with 100 to 240 VAC. We offer two package options: a benchtop version for ease of use, and a compact module for system integration. The benchtop model features an intuitive LCD display with independent controls for output power and temperature, accessible via two front rotating knobs.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Fiber Coupled Narrow Line Laser Source: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1550nm wavelength specification sets source and detector compatibility. The fiber/interface entry (PM1550) must match the connected components.

Technical FAQ
Fiber Type: PM1550 · Connector: FC/APC, Special. 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: 1550nm. 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.
