KOHERAS ADJUSTIK™ system is a compact single wavelength distributed feedback (DFB) fiber laser system designed to enable active wavelength stabilization or thermal wavelength tuning.

The KOHERAS ADJUSTIK™ is available as a turnkey solution with integrated driver electronics and needs only 110/220 V power supply for operation. It offers mode-hop free thermal wavelength tuning or locking over 1 nm by easy operation combined with fast PZT tuning in the kHz range. The system can optionally be designed for PM operation.
