Micro resonator-based frequency combs transfer the laser characteristics from the pump laser to its comb teeth. Any power fluctuations in the pump laser will be amplified in the nonlinear process that creates the comb.
Get the most stable frequency combs in the market with Koheras BASIK
The power stability and noise characteristics of the pump laser dictate the performance of the frequency comb. Lock your frequency comb to our Koheras BASIK fiber laser. They are mode-hop-free and combine low-noise with an ultra-stable all-fiber light source and a decade-long lifetime.
Have a quick look at the noise specification to see if the BASIK would work for you:
|< 0.1||< 0.1|
|Max. phase noise|
|Max. phase noise|
|Appr. 0.7||Appr. 0.7|
|RIN level @ peak|
|RIN level @ 10 MHz|

Unique fiber delivery system
Do you want to mount the laser system in a rack? No problem. With our unique fiber delivery system, aeroGUIDE POWER, you can get light wherever you want. The fiber delivery solution handles high power, preserves the low-noise laser properties, and delivers single-mode light at all wavelengths.
This laser is robust enough for oil rigs yet sophisticated enough for the lab
Our fiber laser design is inherently compact and robust. It is developed for a lifetime of above 10 years in demanding environments where uptime is critical. With failure rates lower than 1%, we proudly deliver the most reliable low-noise lasers on the market. Alignment-free and maintenance-free.
The industrial-grade OEM lasers have a rugged design, a stable performance unaffected by changing environmental conditions, and wide temperature ranges in the field as well as the lab. We deliver lasers to the most advanced laboratories worldwide such as The Laboratory of Photonics and Quantum Measurements at EPFL and the Quantum Optics and Photonics lab at the Niels Bohr Institute.
We have more than 15,000 Koheras lasers deployed in the harshest environments on – and off – the planet. We have lasers on oil rigs, submarines, wind turbines, and even in space. With over 20 years of experience, we know they last. Also in your lab.
