Dr. Leo Hollberg

Biography

Professor Hollberg’s research objectives include high precision tests of fundamental physics applications in laser physics technology. His experimental program in laser and atomic physics focuses on high-resolution spectroscopy, laser-cooled and trapped atoms, non-linear optical coherence effects in atoms, optical frequency combs, optical and microwave atomic clocks, and high sensitivity trace gas detection. He studies laser noise methods that circumvent measurement limitations and develop quantum limited optical detection. The technologies used include frequency-stabilized lasers and chip-scale atomic devices. Based at the Hansen Experimental Physics Laboratory, his research program has strong, synergistic, collaborative connections with the Stanford Center for Position Time. His research directions are inspired by a deeper understanding of fundamental science, which is critical for addressing real-world problems, such as those in environment and energy. Hollberg’s laboratory aims to create amazing new technologies and devices that enable experiments to test fundamental principles with high precision, leading to the development of instruments and sensors capable of ultrasensitive optical detection of atoms, monitoring trace gases, isotopes, and chemicals that impact various fields.
