Laser-based Sensor Design and Development

Laser-based Sensor Design and Development

Internship Description

The project involves design, development, and implementation of a laser-based optical sensor. The sensor will be used to monitor environmental pollutants (e.g., NOx, CO) or greenhouse gas emissions (e.g., N2O, CH4, CO2). The student will work on studying the electromagnetic spectrum of various molecules, choosing the candidate optical transitions, setting up the laser-based optical setup, and performing laboratory measurements to detect species concentration in trace quantities. Advanced sensing strategies, such as wavelength modulation, cavity-enhancement and frequency combs will be utilized. The student will gain expertise in spectroscopy, statistical thermodynamics, machine learning, optical engineering, and mechanical design.​​​


  • Spectral line selection using state-of-the-art spectroscopic models
  • Design of optical, electronic and mechanical components of the sensor
  • Laboratory validations of the sensor performance
  • ​Field testing for trace gas detection
