High-Precision Spectroscopy
High-precision spectroscopy measures the interaction of light with matter to determine molecular structures, energy levels, and dynamic processes with exceptional accuracy and resolution. It plays a critical role in fields such as fundamental physics, atmospheric science, and metrology, enabling precise measurements of atomic and molecular transitions, the detection of trace gases, and the development of highly accurate frequency standards. Optical frequency combs and ultrastable lasers deliver rapid, accurate molecular analysis for environmental, industrial, and fundamental research.
