Frank Tittel

J.S. Abercrombie Professor in Electrical and Computer Engineering

Professor Frank Tittel has been involved in many innovative developments in quantum electronics and laser technology since the discovery of the laser in 1960, ranging from basic research in nonlinear optics, novel solid state and gas laser development, to applied spectroscopy. Current research activities by Prof. Tittel have led to the development of several advanced autonomous laser-based trace gas sensors. The most recent designs utilize state-of-the-art telecommunications technology in the near infrared and quantum cascade lasers in the mid-infrared spectra region to achieve compact, robust and light-weight instrumentation that can be deployed for field applications by NASA, the EPA, NCAR, DOE and NIH.
