We have studied the effects of the intensity difference of the two laser fields on the performance of the coherent population trapping (CPT) atomic clocks. Our experimental results show that there is ...

High-temperature chemistry in laser ablation plumes leads to vapor-phase speciation, which can induce chemical fractionation during condensation. Using emission spectroscopy acquired after ablation of ...

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing ...

A laser-equipped research platform has, for the first time, photographed airflow just millimeters above ocean waves, ...

A low-cost, simple, noncontact displacement sensor using the self-mixing effect inside a cw single-mode laser diode has been developed for modal analysis and defect detection. The resonance ...
