Quantum and nanotechnology are quickly moving from the lab to the real world, significantly impacting many industries.
Quantum computers tackle complex challenges in drug discovery, materials science, and logistics, while quantum communication ensures ultra-secure data transfer, and quantum sensors enhance navigation, imaging, and exploration. In finance, they can contribute to risk analysis and fraud detection.
Nanotechnology works by engineering materials at the tiniest scale, enabling new ways to deliver drugs, diagnose diseases, and improve medical devices. It also drives progress in electronics by making components faster and more compact, and strengthens materials used in aerospace, construction, and energy.
This page gives you a small taste of what is possible.
Quantum Technology
The Koheras HARMONIK HP is our quantum flagship fiber laser system. Available at many wavelengths, these high-power UV, VIS, and nIR fiber laser systems are popular for quantum computing, sensing, metrology, and communications. They are single-frequency, mode-hop-free, and ultra-stable, and deliver high power and narrow linewidth light at the exact atomic transition you need. With over 20 years of experience and more than 20,000 Koheras single-frequency fiber lasers deployed globally, our systems are designed for scalability and reliability.
Quantum Applications
Companies and research labs use Hamamatsu Photonics’ Koheras fiber laser systems for trapping, cooling, Rydberg excitation, and clock transitions for rubidium, strontium, barium, and ytterbium wavelengths. Examples include atomic trapping and cooling, where higher power allows you to cool more atoms. No other commercial system delivers the same high power at key cooling and trapping wavelengths as the Koheras HARMONIK.
Scalable System Architecture
The Koheras HARMONIK HP fiber laser system is scalable, you can mix and match the elements to make a system that fits your application.
The four key elements are:
- Koheras ADJUSTIK DFB fiber laser
- Koheras BOOSTIK HP high-power fiber amplifier
- Koheras HARMONIK frequency conversion
- aeroGUIDE POWER high-power fiber delivery
Koheras fiber lasers can be power-scaled without compromising linewidth, noise, stability, or mode quality, ideal for creating high-quality
Squeezed light
Whether you work with quantum computers, gravitational wave detection, quantum sensing, or perhaps quantum key distribution, you can benefit from an ultra-low noise pump laser and an amplifier that preserves the low noise. With the Koheras BASIK E15 pump laser, you get a stable, narrow-linewidth fiber laser with intrinsically low phase noise.
NV-centers in diamond
SuperK supercontinuum lasers are ideal for exciting and probing NV centers in diamond. Their broad, stable spectrum, spanning visible to infrared, gives you the flexibility to explore both zero-phonon lines and sidebands without changing sources. With high brightness and exceptional stability, the SuperK supports precise, reproducible experiments in quantum optics, sensing, and spin manipulation.
Scientific Metrology
Scientific metrology is the science of precise and accurate measurement, ensuring consistent standards for both research and industry. It plays a crucial role in everything from material science to fundamental physics. Our SuperK supercontinuum white light lasers bring unmatched brightness and a broad spectral coverage to your metrology setup. They deliver stable, high-intensity light from 400-2400 nm and give you precise, repeatable measurements across a wide range of optical components and materials. Whether you are measuring thickness, reflectivity, or spectral response, SuperK gives you the accuracy and reliability your metrology demands.
Graphene and Nanotubes
Graphene and carbon nanotubes have opened exciting new material science and nanotechnology possibilities. To help you explore their unique properties, like strength, conductivity, and flexibility, our SuperK supercontinuum lasers offer the broad, stable light needed for detailed optical characterization. Whether you’re working with Raman spectroscopy, photoluminescence, or absorption imaging, SuperK gives you a reliable tool to support your research.
