NKT Photonics Koheras ADJUSTIK low noise single-frequency lasers

AdjustiK Benchtop Fibre Laser

Rack mountable benchtop, low noise fiber laser featuring ultra-low phase noise and Hz-range linewidth. Standard systems are available at 1550.12nm and 1064.00nm and we offer special systems anywhere in the 1535–1580nm and 1030–1120nm ranges. Depending on the model, output powers are 10-40mW.

The benchtop ADJUSTIK models are based on the Koheras BASIK Module seed technology but supplied in a 19" rack mounted unit with front panel control interface. The standard ADJUSTIK is availabel at powers from 10-40mW, and the ADJUSTIK HP in powers up to 2 W output power


  • Center wavelengths in the 1535–1580 nm and 1030–1120 nm ranges
  • High-power: Up to 2 W
  • Industry-leading low phase noise and extremely narrow linewidth
  • Stable single-frequency operation
  • Wide thermal wavelength tuning
  • Integrated fast wavelength modulation
  • Polarization-maintaining fiber output
  • Robust and maintenance-free


Product Description

The ADJUSTIK system are narrow linewidth, low noise, single frequency fiber laser turn-key benchtop systems based on a truly single mode, single frequency DFB (Distributed-Feedback) Fiber Laser with extremely high frequency stability and low phase and intensity noise.

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. The benchtop models are based on the Koheras BASIK Module seed technology and are upgradable in terms of output power.

The Koheras ADJUSTIK System is available as a turn-key solution with integrated driver electronics and needs only 110/230V power supply for easy operation.

  • Up to >10mW 1030-1120nm, up to 2W 1535-1580nm wavelengths
  • 10GHz, Fast wavelength modulation range, 2.5 times wider thean the previous generation of ADJUSTIK model
  • Long term thermal wavelength stability 0.1pm
  • No need for external piezo driver, ADJUSTIK has integrated piezo driver and function generator
  • Single mode, single polarisation operation
  • Ultra narrow linewidth (<1 kHz@120us, <0.1kHz Lorentzian)
  • Low phase and intensity noise
  • Available in 19" 1U (custom 19" 2U) rack system


This product could be used for the following applications:

  • Fiber sensing
  • Remote sensing
  • Range finding
  • Optical Trapping
  • Laser cooling
  • Research
  • Spectroscopy of Emission and Absorption Lines
