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, 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. We can deliver shot-noise-limited lasers for applications demanding extra low-intensity noise.

Our ytterbium-doped double-clad fibers offer the largest single-mode cores in the world. The high numerical aperture for the pump core/inner cladding lets you pump with high efficiency, even with inexpensive or high-power broad-area emitting pumps. The single-mode signal travels in the large mode area to give high power levels and prevents nonlinearities. Need it packaged? Choose one of our aeroGAIN-ROD or aeroGAIN-BASE modules.
