Observation of Rabi dynamics with a short-wavelength free-electron laser Rabi dynamics between the ground state and an excited state in helium atoms are generated using femtosecond extreme-ultraviolet pulses from a seeded free-electron laser, which may allow ultrafast manipulation of coherent processes...
between light wavelength spectrum and competing defocus on ocular development. This study aimed to quantitatively characterize the combined effect of specific spectrum of light and competing defocus on eye growth in chicks. Methods Animal and study design The care and use of the chicks were performed ...
In many cases, light is not monochromatic, but rather exhibits a substantial opticalbandwidth. It is then often of interest to determine either the peak wavelength or e.g. a the mean wavelength based on the “center of gravity” of the optical spectrum. ...
The observation data from ASO-S shows that white-light flares are not as rare as previously thought, said Gan Weiqun, the chief scientist of the KuaFu-1 mission and a researcher at the Purple Mountain Observatory. The satellite team will continue to combine multi-wavelength observations from oth...

Regular lamps just don't deliver the full spectrum of light your eyes need. The HD Light is different. It uses our own Daylight Wavelength Technology™ to give you something much closer to natural daylight. The result? Colours are truer, details are sharper, and your eyes feel a lot ...
enable the energy of the emitted light to be tuned. Additionally, the electric field perpendicular to the transistor channel creates a potential difference between the layers forming the interface, which shifts the energy of the recombining electrons and holes41,42. The wavelength of light generated...
However, fluo-3 lacks a significant shift in emission or excitation wavelength upon binding to Ca2+, which precludes the use of ratiometric measurements (Figure 19.3.3). Simultaneous loading of cells with fluo-3 and our Invitrogen™ Fura...
The wavelength of light, the numerical aperture of the objective and the diameter of the diaphragm (a wider detection pinhole reduces the confocal effect) affect the depth of the focal plane. When using confocal microscopy to view fluorescence, where up to 90% of the emission light can be ...
