Chromacity OPO

The Chromacity OPO is our flagship product. We are the first company to offer tunable optical parametric oscillator products that cover both the near-IR and mid-IR wavelength regions.

 

Our near-IR OPO generates light across the 1.4 µm – 4 µm region (7100 cm-1 – 2500 cm-1). Wavelength selection is achieved by translation of a PPLN crystal with varying grating periodicity.

 

Our mid-IR OPO makes use of a new generation of non-linear crystals which allows the generation of light across the 5 µm – 12 µm region (2000 cm-1 – 1000 cm-1).

 

Both systems are optically pumped by the Chromacity 1040 HP, which is fully integrated into the optical head to maximise stability and reduce the overall footprint.

The Chromacity OPO delivers high power, broad band coherent light.

 

The near-IR OPO generates few-picoseconds pulse durations which doesn’t require long hours in set up time. Our laser source does not require water cooling and comes with a simple user interface, making it one of the easiest laser sources to operate.

 

For spectroscopy applications and CARS microscopy, there is often a need to tune to several specific wavelengths. The ability to generate light at these longer infrared wavelengths is key to detecting a wide range of solids, liquids, gases. Being able to generate instantaneous broadband light across the 3 – 4 µm wavelength region lends itself to being able to identify and quantify a large number of hydrocarbons using techniques such as FTIR spectroscopy. The same is also true across the 5 – 12 µm fingerprint region where more complex chemical signatures can be readily identified.

Tailored to your needs

With a wealth of expertise in OPO, non-linear optics and optical fibre 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 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 fibre 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”.
