It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about the “pew-pew” factor that makes ...

Atoms are prepared (magnetically trapped) in a particular internal quantum state |1〉 (Fig. 1a). The atom cloud is first illuminated by a coupling laser, resonant with the |2〉–|3〉 transition. With only ...

Yale scientists have uses acoustic waves to amplify light in a new type of silicon laser for photonic ICs, side-stepping the problem of silicon’s indirect bandgap. “Silicon’s intrinsic properties, ...

Researchers have found a new mechanism that fundamentally alters the interaction between optically levitated nanoparticles. Their experiment demonstrates previously unattainable levels of control over ...
