Multimode Single Channel, Benchtop


Multimode Single-Channel Fiber-Coupled Laser Source

  • Multimode Fiber-Coupled Laser Source
  • 50 mW Output Power
  • Ideal for Optogenetics Applications


  • Output Wavelength: 473 nm
  • Multimode FC/PC Fiber Interface
  • 50 mW Power Output
  • Low Noise, Stable Output

The S1FC473MM Fiber-Coupled Laser provides 50 mW of output power and a wavelength of 473 nm, making it an ideal source for many Optogenetics applications. It includes a pigtailed FP laser diode and current controller in a single benchtop unit. The unit's output can also be externally modulated at 5 kHz full depth/30 kHz small signal. The output is a SFS105/125Y multimode fiber terminated at an FC/PC connector. The unit is compatible with our extensive line of Multimode Patch Cables and Optogenetics Equipment.

The front panel includes 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. Refer to the manual on the Documents & Drawings tab for complete operating instructions. 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.

We also offer Multimode Fiber-Coupled LED light sources, as well as other Fiber-Coupled Laser Sources.
