Koheras 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 and with frequency conversion to many other bands.
Reliability is our highest priority and the all-fiber DFB design ensures robust and reliable operation for thousands of hours.

Koheras lasers 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.
