This range of benchtop laser systems is typically offered as rapidly deployable sources for research laboratories that wish to use it as a tool for scientific work and not spend time on setting up a laser system. The benchtop models are based on the Koheras BASIK Module seed technology and are upgradable in terms of output power. The systems are supplied with our NKTP CONTROL software for the control and read-out of laser parameters on a pc such as wavelength, output power, and RIN suppression.

ADJUSTIK POWER versions available with up to 200 mW (E15) and 100 mW (Y10), see data sheets.
C15: Is a Co-doped Erbium/Ytterbium fiber laser for operation in the 1535-1580 nm wavelength range offering the lowest intensity noise (RIN) and is a shot noise limited fiber laser.
X15/E15: Is an Erbium doped fiber laser for operation in the 1535-1580 nm wavelength range offering the lowest phase and frequency noise and narrowest linewidth of the entire laser portfolio. It is often deployed for interferometric sensor applications demanding 10s of kilometers of coherence length and ultra-high frequency stability.
Y10: Ytterbium doped fiber laser system for operation in the 1030-1120 nm wavelength range with narrow linewidth and low intensity noise. This laser is commonly used for laser stabilisation, atomic physics / metrology, spectroscopy, fusion energy, general replacement of conventional Nd:YAG lasers, and many other applications.
Tuning and PM Options
- PM operation: The output of the ADJUSTIK fiber laser is a Single Mode Fiber with PM (Polarisation Maintaing) output to ensure a fixed orientation of the polarisation. This may be required whenever the laser output needs to be externally modulated or frequency converted.
- Thermal wavelength tuning: The Koheras fiber laser systems are per default thermally tunable to enable the user to match and stabilise the laser at a certain wavelength.
- Fast wavelength tuning: This feature can be offered for applications demanding a higher wavelength stability than provided by the free running laser. It enables the laser e.g. to be locked to an external reference such as an atomic transition line or interferometer.
