Spectroscopy, Microscopy Allow Precise Imaging of Optical Frequencies

Facebook X LinkedIn Email
An imaging technique combining spectroscopy with high-resolution microscopy to produce rapid, precise measurements of quantum behavior in an atomic clock has been developed. Physicists believe the technique could improve atomic clock precision and provide a path toward measuring many-body interactions and testing fundamental physics. This is artwork made with JILA’s new imaging technique, which rapidly and precisely measures quantum behavior in an atomic clock. The images are false-color representations of atoms detected in the ground state (blue) or excited state (red). The white...Read full article

    atomic clock
    An atomic clock is a highly precise timekeeping device that uses the vibrations or oscillations of atoms as a reference for measuring time. The most common type of atomic clock uses the vibrations of atoms, typically cesium or rubidium atoms, to define the length of a second. The principle behind atomic clocks is based on the fundamental properties of atoms, which oscillate at extremely stable and predictable frequencies. The primary concept employed in atomic clocks is the phenomenon of...
    optical clock
    An optical clock is a highly precise and advanced timekeeping device that relies on the oscillations of electromagnetic radiation in the optical or ultraviolet part of the electromagnetic spectrum. Unlike traditional atomic clocks, which use microwave frequencies, optical clocks operate at much higher frequencies, typically involving transitions in atoms or ions at optical wavelengths. Optical clocks have the potential to provide unprecedented accuracy and stability in timekeeping. Key points...
    optical lattice
    A periodic structure formed by intersecting or superimposed laser beams. These beams can trap atoms in low-potential regions, forming a pattern of atoms resembling the structure of a crystal.
