GIGAHERTZ LINEWIDTH FIBER LASERS for helium pumping

CYFL-GIGA series are Ytterbium-doped fiber lasers which emit at 1083nm. These special lasers are specially made for helium pumping applications. Optical imaging for medical applications or study of the helium spin in the nuclear field are amongst the large list of applications with this fiber laser.

Helium pumping, nuclear physics or absorption spectroscopy are some of the applications that can be achieved by this patented ytterbium fiber laser. Designed in cooperation with University research team, CYFL-GIGA is stable, robust and easy to use.

CYFL-GIGA series provide a wavelength emission at 1,083µm. They also deliver high power laser beam (20W).

The particular property is the linewidth of 1 or 2GHz, filled with a large number of single longitudinal modes. This allows consequently to achieve high pumping efficiency of gas atomic transition.

The system integrates a master oscillator that can be continuously tuned over 100GHz and can be modulated for locking purposes. The oscillator is then amplified by a stable and high power fiber amplifier up to 20W.

Therefore, at 1083nm, the laser can overlap 3He transition C3 to C9 as well as 4he D0 to D2.

It is coming into a friendly user 3U benchtop. All necessary controls for setting output power and wavelength are located on the front panel.

Easy to use this fiber laser works over hours, which ensure having a great collection of data. The Ytterbium fiber laser does not need maintenance thanks to a complete fiber design. On request, Keopsys provides free support for installation.
