Wikipedia

  1. lasers

    A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow.A laser differs from other sources of light in that it emits light which is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of light with a broad spectrum but durations as short as a femtosecond. Lasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic and free-space optical communication, semiconducting chip manufacturing (photolithography), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment. Semiconductor lasers in the blue to near-UV have also been used in place of light-emitting diodes (LEDs) to excite fluorescence as a white light source. This permits a much smaller emitting area due to the much greater radiance of a laser and avoids the droop suffered by LEDs; such devices are already used in some car headlamps.

  1. Lasers

    An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

Examples of LASERS in a Sentence

  1. Tomas Olson:

    At first we gave him [Asher] chemotherapy intravenous and the ophthalmologist used lasers on the spots [on his eye] and there were responses. He finished chemo in 2015. The problem with retinoblastoma is it can pop up in other places. Over time, he had a few new ones pop up and they werelasered.

  2. Geoffrey Marcy:

    If the Milky Way actually has other intelligent species sending their spacecraft across the galaxy to settle around other stars on other planets, they might communicate using lasers, there could be a galactic Internet not borne by copper wires, not borne by fiber optics, but carried by laser beams crisscrossing the galaxy.

  3. Lauren Boebert:

    I’ve been asked to explain MTG’s belief in Jewish space lasers, why she showed up to a white supremacist’s conference and now why she’s blindly following Kevin McCarthy, and I’m not going to go there.

  4. Tom Painter:

    We measure snowpack wall-to-wall over mountains from aircraft using lasers and spectrometers, from that information, we can then know the full distribution of how much water there is in a mountain snowpack and also how fast it’s going to melt. That’s allowed us then to change forecast errors from being pretty large to very small and really dramatically changed water management in the west.

  5. Lauren Boebert:

    I've been aligned with Marjorie and accused of believing a lot of the things she believes in. I don't believe in this just like I don't believe in [Jewish] space lasers.
