The Koheras single-frequency fiber lasers are ultra low-noise lasers with longitudinal single mode and single-frequency operation. Available in the Erbium or Ytterbium wavelength ranges, the all-fiber DFB design ensures robust and reliable operation for thousands of hours.
Koheras Erbium and Ytterbium fiber lasers offer an unprecedented low phase- and intensity noise level. They are extremely stable and mode-hop free – even under changing environmental conditions. Furthermore, we can deliver shot-noise limited lasers for applications demanding extra low-intensity noise. Also, check out the fiber delivery options.
