Jeffrey S. Pilgrim

Dr. Jeffrey S. Pilgrim is President and founder of Vista Photonics. He formed the corporation in June 2003 to develop and commercialize optical gas sensing technologies. Before starting Vista Photonics, Dr. Pilgrim worked as a Senior Research Scientist in a similar research and development environment where he developed diode laser-based trace sensing techniques including wavelength modulated photoacoustic spectroscopy (PAS), frequency modulated resonance locked PAS, intracavity PAS, and phase modulated external cavity diode lasers (ECDL). He has invented several ECDLs for trace gas detection and telecommunications. While working in Tucson, Arizona, Dr. Pilgrim developed ultra-high sensitivity trace gas sensors based on intracavity laser spectroscopy using diode-pumped solid state (DPSS) laser systems. He has designed and built DPSS systems at near and mid-infrared wavelengths. From 1995-1997 he was a postdoctoral research associate at Sandia National Laboratories in Livermore, California where he worked in gas phase chemical kinetics. His work utilized direct absorption, frequency modulation, and multiple pass absorption techniques. At the University of Georgia, Dr. Pilgrim worked with time-of-flight mass spectrometry using laser spectroscopy in supersonic molecular beams.
