More is Less: Implications of Quantum States for Classical Light Squusing

"Less is more" (less is more) is an idiom in English culture, meaning that simplicity can bring greater meaning. Recently, researchers have extracted the concept of "more is less" from the quantum squeezed state, which is used to guide the regulation of the classical light field, and has made a breakthrough.

High Brightness UV-Visible-Infrared Wide Spectrum Light Source

The research group of Professor Yu Xia of Beijing University of Aeronautics and Astronautics has successfully developed a miniaturized, high-brightness incoherent broad-spectrum light source, whose spectral range covers the ultraviolet-visible-infrared band. The team proposed an orthogonal laser light path to maintain the plasma technology, which effectively suppressed the negative lens deflection effect of the plasma on the laser, and achieved a high-brightness and high-efficiency broad-spectrum light source under laboratory conditions.
