Single Frequency Fiber Lasers

Koheras single-frequency lasers are longitudinally single-mode and offer extremely low phase- and intensity noise levels. Available in the Erbium or Ytterbium wavelength ranges, the all-fiber DFB design ensures robust and reliable operation for thousands of hours.

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.
