Frequency Comb Laser

The core laser technology in the LongPath system was the basis of Nobel Prize-winning work at the University of Colorado and the National Institute of Standards and Technology.  Our eye-safe, long-path laser systems probe the distinct absorption ‘fingerprint’ of many different molecules (methane, H2S, CO2, H2O, and more) across 50,000+ wavelengths (colors) of light. The LongPath team has been working with the technology for almost a decade – first engineering the laser to achieve low system cost and field robustness, and then developing a methodology for long-distance gas detection. LongPath, CU Boulder, and NIST engineers were the first ever to make outdoor fielded measurements using this groundbreaking technology.
