Tara Michele Fortier is a Canadian physicist and Project Leader in the Time and Frequency Division at National Institute of Standards and Technology. Her research considers precision optical and microwave metrology. She was elected Fellow of the American Physical Society in 2022 and awarded the SPIE Harold E. Edgerton Award in High-Speed Optics in 2023.
Early life and education
Fortier attended Concordia University as an undergraduate student, where she majored in physics and graduate summa cum laude in 1998. Fortier was a doctoral researcher at JILA, where she developed pulsed laser systems for precision measurements. Her postdoctoral work involved a joint position between National Institute of Standards and Technology and Los Alamos National Laboratory, where she searched for violations of Einstein's laws.
Research and career
Fortier was made a Project Leader at National Institute of Standards and Technology, where she develops optical and microwave metrology. In particular, Fortier uses phase stabilised mode-locked lasers to synthesise stable optical signals for optical clocks.
Her efforts to create optical clocks have contributed to more accurate measurements of the second. Optical clocks use atoms (e.g. ytterbium and strontium) that oscillate at very high frequencies. Her team at NIST used eight hydrogen masers to keep time when the optical clock could not function. They achieved a ytterbium-based optical clock that only lost 100 seconds over the age of the universe.
