New Koheras lasers for quantum applications

Performance like never before. New wavelengths. Higher power. Lower noise. Narrow linewidth. Industrial reliability. ​

Are you looking for lasers for your work with rubidium, strontium, barium, or ytterbium?

Our new Koheras HARMONIK high-power UV & VIS fiber lasers have got you covered! The Koheras HARMONIK lasers give you access to a wide range of new wavelengths, up to 10 W of power, low noise, and a linewidth below 200 Hz.   

Industrial reliability

We know that uptime is important to you. Our Koheras fiber lasers are inherently stable. They are reliable, alignment-free, and maintenance-free. You can mount them in a rack or place them upside down, they just do their job. Others even trust our Koheras lasers enough to send them into space. And should you need support, we have a team of dedicated engineers ready to help.  

15,000 Koheras lasers have been installed in demanding industrial applications for decades. Now, they are ready to assist you in your quantum research.  

New wavelengths for your quantum research 

You can now get Koheras HARMONIK lasers at the following wavelengths as a standard:  

  • 780 nm, 840 nm, and 1064 nm for rubidium 
  • 317 nm, 813 nm, and 1064 nm for strontium 
  • 532 nm and 1762 nm for barium 
  • 399 nm, 556 nm, 638 nm, 770 nm, and 1064 nm for ytterbium 

Was your wavelength not on the list? Get in touch for other wavelengths.

The graph shows the VIS wavelength capabilities of the HARMONIK. All lasers are pumped by our low-noise fiber lasers in the NIR (not shown), allowing the lasers to be locked to frequency references at either their fundamental or converted wavelengths.

Get inspired

Our Koheras lasers are used in a wide range of quantum applications, such as inertial and gravity sensing, single photon generation, atomic trapping and cooling. Get more examples.

Unique fiber delivery system 

Do you want to mount the laser system in a rack? No problem. With the unique fiber delivery system, 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.
