Features
Thorlabs offers single mode and polarization-maintaining fiber-coupled laser sources that emit in the NIR portion of the spectrum. Each benchtop laser source features both a pigtailed Fabry-Perot laser diode and current controller in a single unit.
Modulation InBNC Female0 to 5 V Max, 50 Ω Remote Interlock Input2.5 mm Mono Phono Jack
Terminals must be shorted either by included plug or user device, i.e. external switch, for laser mode "ON" to be enabled.

These Single Mode Fiber-Coupled Laser Sources conveniently package a pigtailed Fabry-Perot laser diode and current controller into a single benchtop unit. The Fabry-Perot laser diode inside each unit is pigtailed to a single mode fiber that is terminated at an FC/PC bulkhead (wide and narrow key compatible) attached to the front panel of the unit. Thorlabs offers single mode fiber optic patch cables for connecting to the bulkhead on the front panel. To minimize losses, we recommend using a fiber patch cable that is the same fiber type as the fiber-pigtailed laser; refer to the Specs tab for the internal fiber type used for the pigtail. Additionally, to reduce noise from back reflections, we recommend that a hybrid FC/PC to FC/APC cable be used with the FC/PC end connected to the laser source. Also found on the front panel is a display that shows the output power in mW, an on/off key, an enable button, and a knob to adjust the laser power. The back panel includes an input that allows the laser diode drive current to be controlled via an external DC or sine wave voltage source and a remote interlock input. Note: The laser must be off when connecting or disconnecting fibers from the device, particularly for power levels above 10 mW. ![]()
These Polarization-Maintaining Fiber-Coupled Laser Sources package a pigtailed Fabry-Perot laser diode inside each benchtop unit. The laser diode is pigtailed to a single mode PM fiber that is terminated at an FC/PC bulkhead attached to the front panel of the unit. During the pigtailing process, the fiber alignment is actively maintained so that the polarization axis of the laser diode is aligned with the slow-axis of the PM fiber. In addition, the slow-axis of the PM fiber is aligned to the narrow key of the FC/PC bulkhead connector on the front panel of the benchtop unit. Thorlabs offers polarization-maintaining fiber optic patch cables for connecting to the bulkhead on the front panel. To minimize losses, we recommend using a fiber patch cable that is the same fiber type as the fiber-pigtailed laser; refer to the Specs tab for the internal fiber type used for the pigtail.
