• Single Mode Fiber, FC/PC Interface
• Low Noise, Highly Stable Output
• 488 nm Center Wavelength
• TEC Temperature Stabilization
• Interlock Input

The S3FC488 single channel benchtop laser has an integrated TEC element that is used to stabilize the temperature of the FP laser diode, which in turn stabilizes the output power and wavelength of the laser diode for a given drive current. The FP laser diode is pigtailed to a single mode fiber that is terminated at an FC/PC bulkhead connector (wide 2.1 mm key compatible) on the front panel. Also found on the front panel is a display that selectably shows either the output power in mW or the temperature in °C, an on / off key, an enable button, a knob to adjust the laser power (drive current), and a knob to adjust the temperature (TEC current). 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.
