Researchers have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright visible-wavelength ...
NASA's Parker Solar Probe has captured its first visible light images of the surface of Venus. Using its Wide-Field Imager (WISPR) instrument, Parker imaged the entire nightside in wavelengths of the ...
How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...
WASHINGTON — Researchers have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...
(PhysOrg.com) -- Monochromatic light-emitting diodes cover a large part of the visible spectrum with high effi-ciency. For blue light, nitride diodes achieve external quantum efficiencies in excess of ...
