A new guide to extremely powerful light pulses

The first demonstration of the laser in 1960 was rapidly followed by the birth of a new research field: nonlinear optics. The unique coherence properties of stimulated emission, the fundamental physical process of laser radiation, ...

Direct generation of complex structured light

Extension of laser beam structures promises new laser applications. Exploration of how beam structures change during nonlinear frequency conversion processes has drawn increasing interest in recent years. Nonlinear conversion ...

A chip-scale broadband light source in silicon carbide

Optical frequency combs have changed science and technology as we know it. Responsible for measuring things like infrared and ultraviolet light, greenhouse gases, atomic clocks, and disease, optical frequency combs act as ...

An optical chip improved by light

Technology is increasingly moving towards miniaturization and energy efficiency. This also applies to electronic chips. Light, and optics more broadly, are functional in making compact and portable chips. Researchers from ...

Gap solitons break one-dimensional coherent atomic systems

As the core of the light field modulation technologies, optical lattice has highly tunability and is usually used to manipulate the nonlinear matter waves of Bose-Einstein condensate (BEC). At present, the mainstream researches ...
