We introduce a configuration-dependent parametrisation of coherence in Wheeler’s delayed-choice experiment based on the ...

The cochlea decomposes sounds into separate frequency channels, from which the auditory brain must reconstruct the auditory scene. To do this the auditory system must make decisions about which ...

Optical coherence extends beyond lasers, with partially coherent light enhancing imaging, communication, and photonic ...

Waves in the spatio-spectral and -temporal coherence of evolving ultra-intense twin beams are predicted: Twin beams with low intensities attain maximal coherence in the beam center until certain ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...

X-ray free-electron lasers produce pulses of light that are exceptionally bright, making them powerful tools for studying ultrafast chemical reactions, biological processes, or probing the structure ...

Lasers were created 60 years ago this year, when three different laser devices were unveiled by independent laboratories in the United States. A few years later, one of these inventors called the ...
