Are lasers ionizing radiation? What is the wavelength of a wave with a frequency of 4.34 x 1015 s-1? What is the laser diode rate equation? What is the wavelength of a 92.9 MHz radio wave? What is the principle of semiconductor lasers?
Ionizing radiation, in essence, is just a “part” of an atom that flies off at high speeds. The biggest pieces of these bits are alpha particles, which are akin to cannonballs. They are big and heavy (as “big” as a “part” of an atom can be) and do significant damage to any...
Intravital microscopy was performed on a customized near-infrared/infrared multiphoton scanner (TriMScope-II, LaVision BioTec a Milteny Company, Bielefeld, Germany), equipped with three tunable Ti:Sa (Coherent Ultra II Titanium:Sapphire) lasers and an optical parametric oscillator. Time-lapse recordin...
(LEDs) orlasershave recently led to the rapid development of highly efficient white lamps with high color rendition (CRI) and a wide range of color temperatures (CCTs), includingfull spectrum lighting and solar simulators. These developments have helped push SSL technology to be the next ...
However, only free electron lasers, which are rather complex and bulky machines, are considered to be able to generate really high-power THz radiation. Such high-power femtosecond lasers can excite terahertz emissions a thousand times stronger from a plasma formed in air under special conditions. ...
Laser technology can also be used for improving dyeability since it is well known that the UV output from excimer lasers can modify the surface of synthetic fibers. But the use of la‐ ser energy in textile treatment is still uncommon and is generally limited with denim gar‐ ment finishing...
The mission cannot hope to stimulate all aspects of a space mission, such as micro-gravity and exposure to ionizing radiation, project director Boris Morukov admitted. But the crew will experience weightlessness, which can have a debilitating effect long term, deteriorating muscle and bone tissue ...
This was a "laser transmission tower" that utilized high-energy lasers to pierce the air, ionizing the insulated air so that it could act as a conductor. It established an artificial conductive channel between the ground and the ionosphere, guiding the electrical energy from the ionosphere to ...
