About the PULSe Lab

The PULSe (Princeton University Laser Sensing) group conducts research which is primarily focused on the development of mid-infrared laser spectroscopic instrumentation for applications in trace gas detection and chemical sensing. The target applications range from atmospheric chemistry, environmental monitoring and bio-medical research, to industrial emissions and process control.

Our current research activities include:

  • Ultra-sensitive mid-IR laser spectroscopic systems for remote or in-situ, non-invasive, rapid chemical analysis
  • Novel widely tunable laser sources for high resolution molecular spectroscopic applications
  • Distributed laser spectroscopic trace-gas sensor networks

Prof. Wysocki partners with IBM Thomas J. Watson Research Center in Yorktown Heights, NY, to develop an integrated highly sensitive and reliable optical sensors for monitoring methane emissions. The team lead by IBM together with researchers from Princeton and Harvard universities was awarded a $4.5 million U.S. Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E) grant within the “Methane Observation Networks with Innovative Technology to Obtain Reductions” (MONITOR) program that aims at developing innovative technologies to cost-effectively and accurately locate and measure methane emissions associated with natural gas production.
