Dipole trapping

Dipole trapping is fundamental when working with ultra-cold atoms and molecules for, e.g., optical clocks and quantum computers. For dipole trapping, we recommend stable high-power lasers to give you light in well-defined wavelength ranges.

Artificial Intelligence

Get the high power, low noise, and wavelength conversion with the Koheras BOOSTIK HP

With the stable, high-power Koheras fiber lasers, you get the best starting point for a successful implementation of optical tweezers or standing wave-type dipole traps. Due to the 15 W output power, low noise, and single-mode fiber delivery, setting up has never been easier.

Use the Koheras BOOSTIK HP with our efficient and stable wavelength conversion module, the Koheras HARMONIK, to address the dipole trapping wavelengths of your favorite atoms such as strontium or rubidium. Wavelength conversion also quenches any ASE in the laser system and ensures a spectrally pure signal.

With its high power, ASE suppression through conversion, lack of chillers, and fiber-delivered light, the Koheras lasers are ideal for dipole trapping in the lab and the rack.

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 Center of Applied Space Technology and Microgravity at the University of Bremen and the National Ignition Facility at Lawrence Livermore National Laboratory.

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.
