Where to Buy Narrow-linewidth Lasers

Koheras single-frequency fiber 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. The all-fiber DFB design ensures robust and reliable operation for thousands of hours. Koheras lasers are stable and mode-hop-free – even under changing environmental conditions. You can also get shot noise-limited solutions for applications demanding extra low-intensity noise levels.
