Single Frequency Fiber 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.

Koheras BASIK
The Koheras BASIK single frequency fiber lasers are the absolute pinnacle of industrial low noise lasers featuring ultra low phase noise and Hz-range linewidth normally only found in costly scientific systems. Based on a truly single mode DFB fiber laser architecture, they offer ultra stable performance free of mode-hops.
