FSC Series OPOs

OPO, OPADelivers high power, broadband coherent light.

Our 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 FSC series 1040 HP, which is fully integrated into the optical head to maximize stability and reduce the overall footprint.

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.


Features & Benefits

Tunability and high average power enables a broad range of spectroscopic and sensing applications.


(1) Near-IR OPO

Representative instantaneous bandwidth as the OPO is tuned across its full range. Water absorption lines can be observed across the 5.5 – 7.5 μm range.

Good News: FSC Series Ultrafast Lasers for Hire:

Hire one of our ultrafast lasers to experience their power and robustness first-hand. You can now use our femtosecond fiber lasers, or tunable optical parametric oscillators, to accelerate your research without incurring the total cost of ownership.

Our FSC-1040 laser and FSC series OPOs can be drop-shipped and installed remotely, without the presence of an onsite engineer. Our ultrafast lasers are easy-to-use and operational ready straight out of the box – so you spend less time running the equipment, and more time pioneering results.

FSF Series Optical Parametric Amplifiers

Our optical parameter amplifier is a device that precisely converts ultrafast pulses of one band (e.g. 1030 nm pulses coming from FSF series femto-second lasers) into a set of pulsed laser beams tunable in an extremely broad spectrum of wavelengths, ranging from 210nm up to 2600nm. All automated, all software-controlled.opo OPA

Growing number of ultrafast spectroscopy techniques has prompted the need for a robust and reliable, self-diagnostic device. The Optical Parametric Amplifier can be fully compatible with most femtosecond lasers and provides automated tuning across the basic tuning range.


The OPA is a versatile piece of equipment, due to its broad range of tuning and high conversion efficiency. When seeded with a reliable ultrafast laser such as our femto-second lasers, it may find use in many applications like pump probe spectroscopy, non-linear optics & neuroscience.

Non-Collinear Optical Parametric Amplifier

iNOPA™ is a white light continuum-seeded, non-collinear, optical parametric amplifier capable of generating extremely short pulses when pumped by the Model IMPULSETMYb-doped Fiber Oscillator/Amplifier. To generate short pulses the output beam of the Model IMPULSE laser is split into two beams inside the Model iNOPA enclosure. One beam is used to generate an extremely broad continuum seed beam which is then amplified by the second, higher intensity beam from IMPULSETMin a BBO crystal operated in a non-collinear arrangement. Non-collinear amplification preserves the very broad linewidth of the seed beam, which can then be compressed to a pulsewidth as short as 15 fs in a prism compressor. Non-collinear amplification is preferred since the resulting pulsewidth is dependent only on the bandwidth of the seed and not on the pulsewidth of the pump laser. In fact, conversion efficiency is improved by having a longer, rather than shorter, pump pulse because the there is more overlap in time between the two beams.
