Its Bragg diffraction will resemble that of a powder but, with a small enough beam and a typical grain size of around a micrometre, the individual grains can still be separated. Even highly ...

What is Bragg Coherent Diffraction Imaging? Bragg coherent diffraction imaging (BCDI) is a powerful X-ray imaging technique that allows researchers to visualize the internal structure and strain ...

Researchers in Germany have developed a special technique that will allow better control over atomic reflections in quantum ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

Dichroic mirror pulses act like velocity-selective traffic controllers for atoms by directing the particles with correct ...

Quantum sensors can be significantly more precise than conventional sensors and are used for Earth observation, navigation, ...

Photonic crystal surface-emitting lasers or PCSELs are laser diodes that generate laser beams through controlled light wave interaction within a photonic crystal structure. In a recent study, ...

We show that the variation of the Kogelnik efficiency versus Bragg angle depends only on one parameter ... In particular, it is possible to obtain theoretical 100% diffraction efficiency with one ...
