Fermion I Fiber coupled laser


  • 405nm to 1550nm
  • Singlemode fiber
  • Narrow linewidths
  • Adjustable output power
  • Modulation or pulsed
  • High stability, low noise
  • Certified system


The Fermion I Series of Turnkey Fiber Coupled Lasers are designed to make using lasers easy and convenient. You just plug it in and turn it on. No additional power supplies or heat sinks are needed.

These systems have outputs up to 200mW from the end of singlemode fiber. All lasers are temperature controlled for high stability and low noise. A range of discrete wavelengths cover the span from 405nm to 1550nm.

Internally the lasers are coupled to singlemode fiber for that particular wavelength. This gives a spatially filtered output beam with a smooth Gaussian profile. Many of the lasers can oscillate in a single longitudinal mode or narrow spectral line. Options for polarization maintaining fiber also available. Lasers can run in CW, modulated or pulsed mode from zero to full output using the front panel knob or an external voltage source. A one meter length of fiber patch cord is included.

Output of the fiber can be collimated using our Fiber Collimators. They are available in different beam sizes with adjustable focus. Output is diffraction limited with low wavefront error. Please see the Fiber Collimator Series.

Other options include different cable lengths, wavelength combining, fiber splitters and polarization maintaining fiber.
