Fermion II fiber coupled laser


  • 405nm to 1550nm
  • PM fiber
  • Variable output
  • Collimating optics options


The Fermion II 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 output up to 240mW 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 1653nm.

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. 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, Fiber Collimators, wavelength combining, fiber splitter, polarization maintaining fiber and multimode fiber.
