From cosmic rays to CT scans, radiation surrounds us but not all exposure is dangerous. Here’s how to separate fact from fear ...

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Technical University of ...

We developed high-power diode-pumped Nd: YAG 1.064 μm laser with pulse duration of 100 ps, energy of 360 mJ, pulse repetition rate of 200 Hz and divergence of laser radiation at the level 1.3 of ...

The sharp focusing of laser radiation is widely used in many optical devices: photolithography, confocal microscopy, optical memory disks, and optical micromanipulation. Using the Rayleigh-Sommerfeld ...
