A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its ...

Brookhaven National Laboratory physicist Erdong Wang in a basement lab at Stony Brook University (SBU) with the high-voltage polarized electron gun that will put the "e" — or electrons — in the future ...

Ideal for applications such as range-gated or polarization-contrast imaging, LADAR, sensing, and micromachining, the Picasso PF1550PM-30 pulsed fiber laser provides 1.54-µm polarized eye-safe output.

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...

The powerful light field manipulation capability of metasurfaces offers a novel development perspective for the quantum precision measurement. By applying the phase-gradient metasurface (PGM) to ...
