A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
Laser. Members of the Directed Energy and Electric Weapon Systems Program Office of the US Navy, fire a laser through a beam director on a Kineto Tracking Mount, controlled by a MK-15 Phalanx Close-In Weapons System. A laser weapon is a directed-energy weapon based on lasers .
The new research, which was funded by the US Air Force, found a solution to limit the scattering and produce a high-quality, high-powered beam capable of causing major damage to a distant target.
The Peresvet (Russian: Пересвет), named after Alexander Peresvet, is a Russian laser weapon for air defense and anti-satellite warfare. [4] [3] [5] The Peresvet is one of the six new Russian strategic weapons unveiled by Russian President Vladimir Putin on 1 March 2018.
DragonFire uses UK-pioneered beam-combining technology to deliver a laser beam with increased power density, reduced defeat times and increased effective range. This is achieved, in part, through the use of tens of glass fibres; however, the full technical approach remains classified.
Moderate and high-power lasers are potentially hazardous because they can burn the retina, or even the skin. To control the risk of injury, various specifications, for example 21 Code of Federal Regulations (CFR) Part 1040 in the US and IEC 60825 internationally
The Extreme Light Infrastructure (ELI ERIC) is a research organization with the world's largest collection of high power-lasers. ELI operates several high-power, high-repetition-rate laser systems which enable the research of physical, chemical, materials, and medical sciences.
Due to their thermal conductivity, pulsed, rather than continuous wave lasers, are preferred in laser engraving applications. High peak power, low pulse duration lasers are able to ablate material off a metal engraving surface without delivering enough energy to melt the surface. Laser on stainless steel.
These devices can generate high power outputs with good beam quality, wavelength-tunable narrow-linewidth radiation, or ultrashort laser pulses. In 2012, Nichia and OSRAM developed and manufactured commercial high-power green laser diodes (515/520 nm), which compete with traditional diode-pumped solid-state lasers.
Flashlamp, laser diode. Material processing, rangefinding, laser target designation, surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam). One of the most common high-power lasers.
