Koheras Single Frequency Lasers

The Koheras 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, and are delivered as fully integrated systems for the industry and scientific community. They offer an unprecedented low phase and intensity noise level, very high stability and mode-hop free inherent single frequency output – both under stable and uneven environmental conditions. Furthermore, shot noise limited solutions are available for applications demanding a very low intensity noise level.
