Koheras single-frequency fiber lasers

Koheras single-frequency lasers are longitudinally single-mode with ultra-low phase and intensity noise. They are available in erbium, ytterbium, and thulium wavelength ranges, with frequency conversion to many other bands.

Reliability is our highest priority, and the all-fiber DFB design ensures mode-hop-free and reliable operation for thousands of hours.

Our all-fiber DFB design ensures robust, mode-hop-free operation with unmatched stability – even under changing environmental conditions. For applications requiring ultra-low intensity noise, shot noise-limited options are available.
