Quantum Fluctuations Yield 20x Boost in Laser Interactions Without Extra Power

Chinese researchers used bright squeezed vacuum, a quantum light state, to amplify nonlinear laser interactions by over 20x at the same average energy, reducing damage risk and enabling tunable interaction strength through light statistics—potentially advancing attosecond science and ultrafast optical technologies.

Self-organizing laser beam enables ultrafast, high-res brain imaging

MIT researchers reveal a laser that self-organizes into a stable pencil beam inside a multimode fiber under precise on-axis high-power conditions, enabling ultrafast, high-resolution 3D imaging of the blood–brain barrier and real-time tracking of drug uptake without fluorescent tags—potentially speeding brain-targeted therapy research by about 25x and opening paths to imaging neurons and other tissues.
