Keopsys CYFL-KILO Ytterbium Fibre Laser

Single frequency ytterbium fibre laser for scientific applications


CYFL-KILO: Ytterbium fibre lasers are based on an MOFPA design. Therefore, they integrate an ultra low noise and narrow linewidth seed (<70kHz) laser which is amplified through several stages of a highly stable ytterbium-doped fibre amplifier. Also, these lasers can be thermally tuned in wavelength over 200MHz, and their central emission line can be modulated for locking purposes.


  • 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.

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