The Fabry-Perot laser diode inside each unit 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. 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 voltage source and a remote interlock input. All of our fiber pigtailed lasers utilize an angled fiber ferrule at the internal laser/fiber launch point to minimize reflections back into the laser diode, thereby increasing the stability of the laser diode's output.
