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 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. Rhode Island Gov. Gina Raimondo:

    This is not the time for social gatherings, the economic devastation in this state and every state around this country is untenable. So I am focused like a laser on work, getting people enabled to work.

  2. Jackie Stewart:

    She could take down 26 racing cars on the same track at the same time on one single stopwatch. As did Betty Hill, Pat Surtees, Bruce McLaren’s wife, Jochen Rindt’s Bruce McLaren wife, it was Nora Tyrrell and Helen Stewart timing for the whole team, but at the same time in the race doing a lap chart for 26 cars. Here’s the sharpness, a laser brain... and then suddenly not remembering the most simple thing.

  3. 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.

  4. Modern Round CFO Ron Miller:

    We are a one-of-kind virtual shooting entertainment concept. We combine high-tech gaming with uniquely designed laser technology-based replica firearms, along with top-of-the-line food, beverages and service. The concept is based on the ‘ savor, sip and shoot ’ experience of our guests, philosophically, people are looking for something to do — especially once they leave college.

  5. John Ratcliffe:
