Optical Parametric Oscillators

Tunable Laser Sources

Chromacity has developed a range of tunable laser sources which span the short to long IR wavelength regions.

 

The Chromacity Auskerry (formerly the Near-IR OPO) is our flagship tunable optical parametric oscillator (OPO) which generates light across 1.4 µm – 4.2 µm (7150 cm-1– 2400 cm-1).

 

The Chromacity Haskeir (formerly the Mid-IR OPO) is powered by a new generation of non-linear crystals which generate broad bandwidth coherent light across the long wavelength regions, between 4.5 µm – 12 µm (2200 cm-1 – 850 cm-1).

 

Both picosecond OPOs are optically pumped by our high power Chromacity 1040, which is fully integrated into the optical head to maximise stability and reduce the overall system footprint. Fiber delivery capability reinforces the inherent stability of our OPO systems and seamless OEM integration for industrial applications.

 

Chromacity is the first laser manufacturer to remotely install ultrafast OPOs. Patent protected manufacturing and design processes have driven Chromacity to build truly robust and affordable OPO systems with drop-ship capability and plug & play functionality.

What’s in a name?

 

We’ve been inspired to rename our optical parametric oscillators after Scottish lighthouses. Lighthouses are one of the earliest forms of harnessing light to protect people and safeguard industrial operations. We’re searching for the modern-day explorers who can use our tunable light sources to push the boundaries of scientific research and develop new technologies which protect people, assets and the environment.

 

By emitting light from our OPOs, we aspire to emulate the profound societal impact that lighthouses have served communities for centuries.

The Chromacity OPOs deliver high power, broad band coherent light. The Chromacity Auskerry can be integrated into an FTIR spectrometer, providing the ability to interrogate multiple chemical signatures in real time (at a high resolution). Our Chromacity Auskerry OPO has a broad bandwidth across the 3µm-3.5µm to quantify gases such as of methane, ethane and benzene in a single measurement with resolutions of 0.05cm-1. The high powers of the Chromacity Auskerry have demonstrated open-path stand-off detection measurements beyond 100m.

Spectroscopy across the fingerprint regime provides that ability to characterise volatile organic compounds with complex chemical signatures and the high brightness of our Chromacity Haskeir OPO spans the 4.5 – 12µm and can be used in a number of these set-ups. It can also been used to characterise and differentiate between compounds, such as VX and Sarin, as well as pharmaceutical powders such as aspirin and ibuprofen

With a wealth of expertise in optical parametric oscillator technology, non-linear optics and optical fiber delivery, the Chromacity team are able to consider a wide range of options to help meet your requirements. If you have a specific request, please don’t hesitate to contact us.

Customer Feedback

“I just wanted to thank you from our entire team. You’ve played a big role here at Bridgewater State University and now we can’t wait to make the best of your one of a kind OPO system for sensing and imaging in our new integrated-photonics training facility”.

– Prof. of Physics, Laser Lab, Bridgewater State University

“Using the online conference on Zoom, our research group completed the installation, startup, and characterization of the Chromacity OPO in our laboratory under the remote guidance of engineers in the UK. The high integration and easy operation of the OPO system make remote installation possible, which overcomes the trouble caused by Covid-19. At the same time, the OPO provides high output power and a wide output spectrum, which gives us an excellent light source for the material characterization using second harmonic generation (SHG) and other nonlinear optical effects. It is worth mentioning that in the process of equipment installation and usage, Chromacity provides detailed and effective solutions to the technical problems we encounter, and is a reliable research partner.”

“I acquired one of the first Chromacity optical parametric oscillator (OPO) systems  in 2015 to enable my work on infrared superconducting single-photon detectors with the QuantIC quantum technology hub.  This source provides picosecond pulses from 1 to 4 micrometre wavelength with a fiber coupled output.  We have built a unique single photon detector characterization setup based around the OPO.  This has enabled us to carry out robust characterisation of photon counting performance in the challenging infrared region and proof-of-concept photon counting LIDAR experiments. Chromacity Ltd have provided excellent close support, assisting with installation in our new lab and responding promptly to technical enquiries. Chromacity Ltd is a very valuable partner for our research effort”.

– Prof. of Photonics, University of Glasgow


‘The engineering team helped us by understanding our specification and delivering an OPO system with a customised fiber coupling module. The software for controlling the OPO was also modified for our requirements. The team have been highly responsive with all of our enquiries and the remote installation worked perfectly. We had the system up and running and ready to use in our experiments in no time at all.”
