The Koheras single-frequency fiber lasers are ultra low-noise sources with longitudinal single mode and single-frequency operation. The lasers are based on a DFB design ensuring robust and reliable operation. They are delivered as fully integrated systems for industrial and scientific applications.
Koheras offers an unprecedented low phase- and intensity noise level, very high stability, and a mode-hop free inherent single-frequency output – even under changing environmental conditions. Furthermore, we can deliver shot noise limited solutions for applications demanding an extra low-intensity noise level. Also, check out the fiber delivery options.
