ultraphotons high-precision-laser

Ultraphotons offers new innovative laser technologies for precise multi-compound gas sensing, especially in the 3-5 µm infrared wavelength region.


The CW-OPO and CQN COMB light sources of Ultraphotons are designed for demanding trace gas monitoring applications that require detection and quantification of multiple compounds with high precision, selectivity, and speed. Potential applications include

In particular, one of the most important molecular fingerprint regions, i.e. the atmospheric window at 3-4 µm, can be addressed for highly sensitive gas sensing applications. This spectral region is difficult to reach with conventional laser sources.



Widely tunable, continuous-wave (CW) optical parametric oscillator (OPO) for tunable laser spectroscopy in the 3-4 µm molecular fingerprint region. Our cost-efficient and robust CW-OPO technology provides a combination of large wavelength tuning, narrow-linewidth, and high output power.


Patent pending optical frequency comb technology based on cascaded quadratic nonlinearities (CQN). While a conventional laser emits just one wavelength at a time, an optical frequency comb generator produces thousands of discrete laser wavelengths simultaneously from a single instrument. Unlike most other frequency combs, the CQN approach requires no femtosecond lasers – a simple continuous-wave pump laser is enough. The CQN comb can be tailored for nearly any wavelength in the near- and mid-infrared regions.

About Us

Ultraphotons is a spinout from the University of Helsinki in Finland, developing compact laser instruments to detect polluting gases in the air.

Our research background goes back to 2013 when our team started to work on a new technology for optical frequency comb generation at the University of Helsinki. The team has world-leading research knowhow in photonics and enabling laser technology, complemented with international business expertise from start-ups to large international corporations.

Ultraphotons’ patent pending photonics innovation combines the superior characteristics of laser precision and speed with the key characteristics of infrared multi-compound detection techniques.
