Researchers present simplified, improved scheme for precision measurement using lasers

Within atomic and laser physics communities, scientist John "Jan" Hall has become a key figure in the history of laser frequency stabilization and precision measurement using lasers. Hall's work revolved around understanding and manipulating stable lasers in ways that were revolutionary for their time. His work laid a technical foundation for measuring a tiny fractional distance change brought by a passing gravitational wave. His work in laser arrays awarded him the Nobel Prize in Physics in 200...
