fs/ps Coherent Anti-Stokes Raman Spectroscopy
See inside the extreme.
Femtosense builds ultrafast laser systems that measure temperature and species concentration where no probe can survive — from rocket combustors to plasmas to cryogenic hydrogen.

Capabilities
A diagnostic for problems that have none.
Non-intrusive, calibration-free, and quantitative — fs/ps CARS delivers single-shot thermometry and species measurements with picosecond resolution in environments that destroy thermocouples and overwhelm conventional spectroscopy.
Temperature
Single-shot thermometry from cryogenic 20 K to over 3000 K.
Species concentration
Quantitative measurement of H₂, CH₄, CO₂, N₂, O₂ and more.
Picosecond resolution
Time-resolved diagnostics that freeze turbulent dynamics.
Where we measure
From rocket flames to plasmas.
- Aerospace combustors & propulsion
- Low- and high-temperature plasmas
- Cryogenic hydrogen & cold flows
- Metrology & dynamic temperature standards
Bring quantitative measurements to your hardest problem.
Whether you're characterizing a next-generation propulsion system or a hydrogen burner, we'd like to hear what you're trying to measure.
