They are the strongest lasers in history, and their beams are helping scientists explore the structure of the universe.In a research laboratory at the University of Michigan, bright green light fills the vacuum chamber of a technology giant. It is the size of two tennis courts. The walls are shielded with 60 centimeters of concrete to prevent radiation leakage, and workers wear masks and hairnets ...
With funding from the National Science Foundation of the United States, researchers at the University of Rochester are developing photonic chips that use quantum technology called "weak value amplification" to replace mechanical gyroscopes used in drones, enabling them to fly in areas where GPS signals are obstructed or unavailable.Using this quantum technology, scientists aim to provide the same ...
The research team led by Professor Gao Xiaoming of the Chinese Academy of Sciences Hefei Institute of Physical Sciences has improved the measurement accuracy of atmospheric greenhouse gases by using erbium-doped fiber amplifier assisted laser heterodyne radiometer.The study was published in the Journal of Optics and was selected as an editor's selection.LHR is renowned for its high sensitivity and...
High power optical frequency combs play a crucial role in nonlinear precision spectroscopy, extreme ultraviolet optical frequency comb generation, nuclear atomic clock research, and other fields. Fiber optic femtosecond lasers are the preferred solution for achieving high power optical frequency combs due to their simple structure, stable performance, and easy amplification.However, due to the una...
