NKT Photonics has introduced a new generation of its Koheras AdjustiK narrow linewidth benchtop fibre laser. The device is based on a single frequency distributed-feedback fibre laser with high frequency stability and low phase and intensity noise.
The Koheras laser provides inherently single frequency operation both under stable and uneven environmental conditions. The new generation of Adjustik systems offers several control and monitor options for laser operation with either direct access from the front panel or via a PC using the supplied GraphiK program. Higher power systems are available using the Koheras BoostiK platform with up to 2W of output power. The benchtop models are based on the Koheras BasiK seed technology, offering the possibility to upgrade the output power or change the laser wavelength. Applications include interferometric sensing, LIDAR, and basic research.
