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. Montoya Major:

   My initial thought, when I found out I was pregnant, was, What am I going to do with a child ? i was living in Florida, away from all my family and friends. Having kids was never a thought of mine. I wanted to pursue my degree and establish a career. MOM SHOCKED TO FIND POLICE AT HOUSE PLAYING BASKETBALL WITH HER SONS I knew that now, my entire thought process would have to be re-evaluated, and I needed to figure out what to do next, she continued. Though the director of Majors academic program told her it would be nearly impossible to complete her studies with two babies on the way, she remained laser-focused on her studies, attending class every single day literally until the day I gave birth, as per Facebook. In May 2018, little Makenna and Makinlee were born early via C-section. One week later, Montoya Major was back in the classroom. The proud mom told Fox News that she never would have been able to weather the challenging season of life without the support of family and friends, especially her dad. Her father raised her as a widow, and always championed the importance of education as his daughter was the first in their family to attend college. Throughout this entire journey my father encouraged me the most although he was not physically there. My father and I are very close and have always been inseparable after my mother passed when I was young, Montoya Major told Fox News. Whenever I had an episode of wanting to quit school he always encouraged me that it would be worth it in the end. Nevertheless, the collegian would later reflect on that journey as the hardest year of my life balancing her studies and clinical rotations with caring for two newborns on her own.
