The AdjustiK™ system are narrow linewidth 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.

The Koheras AdjustiK™ System is a single stage amplified system with up to 200 mW of output power, whereas the Koheras BoostiK™ System is based on multi stage amplification with up to 15 W of output power.

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 Koheras GraphiK™ software for the control and read-out of numerous laser parameters on a pc such as wavelength, output power, and RIN suppression.

A part from interferometric sensing and LIDAR, these laser systems are very useful sources for various scientific applications (more information available in the application section).

The advantages of Koheras fiber lasers are:

• Longitudinal single mode & single frequency operation
• Burst noise and mode-hop free operation
• Unprecedented low frequency and intensity noise
• Shut-noise limited solutions
• Ultra narrow linewidth  (Hz range)
• High free-running wavelength stability (~ 0,1 pm / °C)
• Linear and mode-hop free thermal tuning (up to 800 pm)
• Piezo tuning capability (kHz modulation e.g. for frequency locking)
• Polarisation Maintaining Output
• All-fiber coupled solutions and limited maintenance 
• Remote digital control
• Active RIN suppression
• Multiplexing capabilities & modularity
• Low power consumption
• Very compact and robust design
