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.
The front panel of each laser source displays the output power in mW, an on/off key, an enable button, and a knob to adjust the laser power. The back panel includes a BNC 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. 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.
