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
