Wikipedia

  1. Laser

    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. 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, semiconducting chip manufacturing (photolithography), and free-space optical communication, 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 (LED's) 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 LED's; such devices are already used in some car headlamps.

  1. laser

    A laser is an electronic device that generates a highly concentrated, amplified beam of light using stimulated emission of electromagnetic radiation. The term laser is an acronym for "Light Amplification by Stimulated Emission of Radiation". Lasers can come in many different sizes and different types are used in numerous applications in fields such as science, industry, medicine, and consumer electronics. The beam produced by a laser is extremely focused, allowing it to be used for precise and high-intensity tasks.

  1. Laser

    A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation. Lasers differ from other sources of light because they emit light coherently. Its spatial coherence allows a laser to be focused to a tight spot, and this enables applications like laser cutting and laser lithography. Its spatial coherence also keeps a laser beam collimated over long distances, and this enables laser pointers to work. Laser also have high temporal coherence which allows them to have a very narrow spectrum, i.e., they only emit a single color of light. Their temporal coherence also allows them to emit pulses of light that only last a femtosecond. Lasers have many important applications. They are used in common consumer devices such as DVD players, laser printers, and barcode scanners. They are used in medicine for laser surgery and various skin treatments, and in industry for cutting and welding materials. They are used in military and law enforcement devices for marking targets and measuring range and speed. Laser lighting displays use laser light as an entertainment medium. Lasers also have many important applications in scientific research.

    The Internet: The Internet is a global communication system for transmitting data across different types of media. It can be described as a global network that connects different networks, whether they are private, public, commercial, academic, or government networks, using wireless technologies or optical fibers. The computer uses the control protocol Transmission / Internet Protocol., which provides it with a host that enables it to access the Internet, and the Internet has raised the standards of regular networks to global standards.

Examples of laser in a Sentence

  1. Chief Executive Kurt Graves:

    We could go public right now if we wanted but strategically and operationally it is best to stay private for now because we are well-financed and having a laser focus on execution when you are getting ready to launch a diabetes drug is a big benefit, at some point I'm sure we will be a public company. We hope when we do that we will have launched our first medicine and we have multiple exciting products coming through in the pipeline.

  2. Saj Khan:

    Dr Homer said. The laser treats only the iris and does not enter the pupil or treat any portion of the inside of the eye where the nerves affecting the vision are located. The company is still in the fundraising stage but hopes to have completed clinical trials within several years. And the cost of turning your brown eyes blue ? Dr Homer says Stroma Medical would charge around $ 5,000( £ 3,120) for the procedure. Industry skepticism Industry reaction to the process has been muted. Ophthalmologists who deal with people's eyes, Dr Homer concedes, have every right to be skeptical for the simple fact they are dealing with one of the most sensitive organs in the human body. Saj Khan, an ophthalmologist at the London Eye Hospital, told CNN the treatment raised some red flags. ' The main concern with any procedure that involves releasing pigment inside the eye is that the pigment can clog up the normal drainage channels which can in turn cause the pressure inside the eye to go up, if that happens significantly enough, for long enough, it's how patients develop glaucoma.

  3. Demi Lovato:

    I was getting laser hair removal … down south … and the lady started talking about how her kid was a huge fan, boundaries.

  4. Nick Cannon:

    Yesterday, it was a little easier than today because yesterday I was so laser-focused and even numb.

  5. Emily Weiss:

    Over the past two years, we prioritized certain strategic projects that distracted us from the laser-focus we needed to have on our core business : scaling our beauty brand, we also got ahead of ourselves on hiring. These missteps are on me.
