Are you looking for a laser for rubidium cooling for applications such as gravimeters, quantum computers, or inertial sensors? A mode-hop and ASE-free low phase-noise laser that ensures efficient cooling? A laser with a high power to maximize the number of cooled atoms?
Have it all with the Koheras HARMONIK
We suggest you go for our high-powered, frequency-doubled Koheras HARMONIK fiber laser system. This system is mode-hop-free and gives you a unique combination of high power, low noise, excellent beam quality, and a narrow linewidth. In addition, the frequency conversion efficiently suppresses any Amplified Spontaneous Emission (ASE) because the power is too low to be converted in the nonlinear process.
Use the Koheras BOOSTIK HP with our efficient and stable wavelength conversion module, the Koheras HARMONIK, to address the dipole trapping wavelengths of, e.g., rubidium.
Get an overview of the noise data:
| HARMONIK | H78 | H81 |
| Center wavelength | 770-785 nm | 789-845 nm |
| RIN peak | ≈ 0.7 MHz | 0.5 – 2.0 MHz |
| RIN level | < -97 dBc/Hz @ peak < -132 dBc/Hz @ 10 MHz | < -100 dBc/Hz @ peak < -140 dBc/Hz @ 10 MHz |
| Optical S/N (50 pm res.) | > 70 dB | > 70 dB |

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 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 Quantum Hub at the University of Birmingham.
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.
