Description

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

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