Koheras HARMONIK – new laser system for cutting-edge quantum optics

January 29, 2019

Birkerød, Denmark (January 28, 2019), NKT Photonics is happy to introduce the Koheras HARMONIK system: A high-power, frequency-converted and ultra-low noise laser system offering up to 7 W output. With a market leading low phase noise and narrow linewidth at 775-780 nm, it is ideal for ultracold atom applications.

The laser system is completely fiber monolithic and maintenance-free with an industrially rugged air-cooled package – ready to handle 24/7 operation in laboratories as well as industrial environments.

With market leading low phase noise and narrow linewidth, the HARMONIK laser system is ideal for ultracold atom applications.

“We are truly excited about the new Koheras HARMONIK series. With the very stable, frequency-doubled system, we open up for a wide range of experiments within cutting-edge quantum physics”, says Søren Løvgreen, Product Line Manager for Koheras lasers. “The ultra-low phase-noise and relative intensity noise is especially important for atomic trapping experiments but has many other applications in areas such as metrology and LIDAR”.

Ideal for quantum optics

Quantum optics is a critical strategic technology in security as well as civil applications. Important quantum optic techniques such as Doppler laser cooling of atoms and squeezed light require low-noise, narrow-linewidth lasers, like the HARMONIK system. Other uses of the HARMONIK include:

  • Quantum optics, computing and phenomena such as optical trapping, optical lattice, Bose-Einstein condensate, atom interferometer, squeezing etc.
  • Nonlinear optics pump source e.g. second harmonic generation, parametric processes
  • Laser-based metrology such as precision laser interferometry and spectroscopy
  • Optical heterodyning and coherent communication
  • Coherent beam combining
  • Optical length and frequency standards
  • High precision spectroscopy
