Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics ...

That is because previous experiments with monochromatic light have shown that plants mainly use light from the visible wavelengths (400 to 700 nm) for photosynthesis, and that light with shorter ...

Dr. Franck Marchis, a senior planetary astronomer and director of Citizen Science at the SETI Institute, and Dr. Lauren Sgro, outreach manager for LaserSETI and astronomer at the SETI Institute, ...

Researchers introduce a cost-effective method for producing optical Fresnel zone plate lenses, using colored photoresists for ...

Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...
