Keopsys CYFL-KILO Ytterbium Fibre Laser

Single frequency ytterbium fibre laser for scientific applications


CYFL-KILO stands for Ytterbium fibre laser with kilohertz linewidth. These lasers provide a longitudinal single mode and frequency output laser beam. These lasers series deliver up to 20W with low phase noise and low Relative Intensity Noise.


  • Narrow linewidth
  • Single frequency laser
  • 1064nm and 1083nm standard operating wavelengths
  • Output power up to 20W
  • Ultra low phase noise and RIN
  • Excellent SMSR
  • Diffraction limited output
  • Random or linear polarisation

The narrow linewidth fibre laser provides an output power up to 20W with an excellent power stability. The laser can be monitored by pump diode current or with the output power value (APC option) thanks to an embedded large dynamic photodiode.

Different central wavelengths are available in standard, 1030nm, 1064nm, 1083nm, and others on request. The ytterbium fibre laser can be randomly or linearly polarised. For applications like atomic trapping, or interferometry where a linear polarisation is needed, then the CYFL-KILO polarisation is highly stable.

Reliability and maintenance free are defining this single laser. Coming as an entirely integrated turnkey benchtop, which can be driven directly from the front face. The systems offer different controls mode either from the front face or via RS232.

Lumibird ytterbium fibre laser is manufactured for scientific applications as interferometry, quantum optics, metrology, atom trapping. Lumibird uses its knowledge and high-quality manufacturing process to produce a stable and reliable narrow linewidth fibre laser.

No installation is required as the fibre laser is easy to use, however, on request CohSci provides support for its first start.
