About

Prof. Porat received his BSc and PhD degrees in Electrical and Electronics Engineering from Tel Aviv University in 2007 and 2014, respectively. During his PhD he theoretically developed nonlinear optics analogues to coherent atomic processes and demonstrated them experimentally, facilitating novel phenomena attractive for optical frequency conversion, including adiabatic frequency conversion. He also developed the Airy beam laser and generalized adiabatic nonlinear optics.

Prof. Porat spent two years as a Postdoctoral Fellow at the Weizmann Institute of Science, and three years as a Postdoctoral Research Associate at JILA. At the Weizmann Institute he used ultrafast and nonlinear optics methods, together with a strong-field physics technique called electron holography, to resolve the attosecond-scale temporal properties of the quantum tunnelling process. His research at JILA was centered on the development of the extreme ultraviolet frequency comb laser. His work made it possible to overcome effects detrimental to extreme ultraviolet generation, and achieve record power levels.

Prof. Porat has been a faculty member at the University of Alberta since 2018.

Research

Prof. Porat studies laser physics, ultrafast and nonlinear optics, laser-matter interaction and atomic physics, and how to apply these fields to developing novel quantum technologies and exploring fundamental physics. The main thrusts in his lab are the development of room temperature quantum technology based on nuclear spins in noble gases, standoff quantum sensing of gases, and development of novel frequency comb lasers for quantum sensing and metrology across a wide range of optical frequencies. The techniques he uses and develops span a wide range of disciplines, including ultrafast and nonlinear optics, laser stabilization, high power fiber lasers and amplifiers, atomic spectroscopy and coherent control.

Long term goals of his research plan include improving highly sensitive quantum magnetometry and achieving direct optical nuclear spin polarization of noble gases. Highly sensitive magnetometry is widely applied in geophysical exploration for natural resources, space exploration, biomedical diagnostics, petrology and paleomagnetism, (low-field) nuclear magnetic resonance spectroscopy, and tests of fundamental physics such as searches for dark matter axions. Direct optical nuclear spin polarization (hyperpolarization) of noble gases would remove a major bottleneck for advancing pulmonary MRI and quantum magnetometry. Another goal is the development of highly sensitive standoff laser-based quantum sensing of gases, to be used for environmental monitoring. Prof. Porat is also developing highly stable lasers for portable atomic clocks.
