Two-dimensional control of light with light on metasurfaces
... Ideal performance requires a thin film or metasurface of deeply subwavelength thickness that absorbs 50% of a single beam illuminating the structure. Exploiting that the nanostructure of metasurfaces can be carefully engineered to achieve suitable optical properties and, guided by numerical modeling, ...

... The acronym LASER stands for Light Amplification by Stimulated Emission of Radiation. In contrast to conventional light sources a laser is monochromatic and coherent over a long distance. These characteristics are usefull for many applications in science where e.g. constant beamwidths are demanded. ...

Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
