There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...
Is infrared light made of mechanical waves? What are the different types of infrared waves? How do electromagnetic waves work? How are mechanical waves produced? How do infrared lasers work? How are standing waves produced? How are electromagnetic waves produced in an antenna?
Other lasers, such as diode lasers, are very weak and are used in today’s pocket laser pointers. These lasers typically emit a red beam of light that has a wavelength between 630 nm and 680 nm. Lasers are utilized in industry and research to do many things, including using intense laser...
In submillimeter waves, astronomers can observe universe's "natural lasers," regions where highly charged electrons emit laser light as they discharge some of their energy, said Gay. These natural lasers, sometimes calledmasers, are usually observed in a special type of pulsating variable stars call...
The basic rule is that the tools you use have to be smaller than the things you're using them on.Photo: Inside an atom: electrons are the particles in shells (orbitals) around the nucleus (center).And the same goes for science. The smallest thing you can see with a microscope is ...
Some types of holograms use lasers that produce different colors of light as well. Depending on the type of laser you're using, you may also need a shutter to control the exposure. Lenses: Holography is often referred to as "lensless photography," but holography does require lenses. However...
flexible lighting solutions. Solid-state lasers are now commonly found in applications from medical to industrial. Light weight, compact light sensors are found in devices as diverse as cellphone cameras, bar code scanners, printers, DVD players and automotive sensors. Finally, the emerging field of...
Most modern interferometers use laser light because it's more regular and precise than ordinary light and produces coherent beams (in which all the light waves travel in phase). The pioneers of interferometry didn't have access to lasers (which weren't developed until the mid-20th century) so...
