A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...

The US Army has conducted a combined live-fire exercise at Fort Sill, Oklahoma, integrating high-energy laser systems with ...

Oxford scientists lead breakthrough in quantum materials that could pave the way for advanced quantum technology ...

Laser technology is used in many areas, where precise measurements are required and in communication. This means that they ...

By comparing optical clocks in six different countries, researchers have taken a major step toward establishing a new global ...

Laser pushed sails—ultrathin need reflective structures that are square meters but weight a gram. If the sails and the payload each weigh a gram, such a spacecraft could accelerate to one fifth of the ...

Now, after the launch of the third-generation 200G/lane CPO, Broadcom has telegraphed its commitment to developing a fourth-generation 400G/lane solution. That marks a steady progression of optical ...

Timekeeping has reached an unprecedented level of precision with the advent of optical lattice clocks. These clocks, which use laser-cooled atoms trapped in a grid-like structure, are so accurate that ...

Atoms with narrow-linewidth transition trapped within the Lamb-Dick regime of optical lattice are proposed be used as laser gain medium to build a laser. The gain medium atoms can be the ...

In a 2022 experiment, parts of a strontium optical lattice clock at JILA separated by just a millimeter in height measured a time difference on the order of 0.0000000000000000001 (10 –19).

Optical atomic clock achieves record accuracy redefining the second 21 Jan 2025 Germany’s PTB develops clock that “ticks” at laser frequency 100,000x faster than microwave cesium clocks. Ion trap of ...

PTB scientists have developed various optical clocks, including single-ion and optical lattice clocks, that push the boundaries of precision. A recent breakthrough at PTB demonstrated record-breaking ...
