Nonlinear optics is the study of how intense light interacts with matter. The optical response of a material usually scales linearly with the amplitude of the electric field. At high powers, however, ...

Optics and photonics is the study of the fundamental properties of light and harnessing them in practical applications. Optics and photonics covers the entire electromagnetic spectrum from high-energy ...

Red dot sights have proliferated into every corner of the firearms world in recent years and, today, they are better than ever. These non-magnified optics, which use a battery to project a luminous ...
