laser, optical masernoun
an acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light
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.
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.
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.

The question is really can we be laser focused rather than generic across the country? in other words, can we use our data in a laser-focused granular way to really look at what's happening on the ground and adjust our public health messages based on what is actually needed by the number of cases and the work that we're doing with the communities.
If laser treatments are too pricey, or the hair is not dark brown or black (and therefore not a goodcandidate for laser treatments), then go forshaving over waxing. Waxing has the highest risk of causing in-grown hairs that can be painful and even get infected with MRSA.
The scanning LIDAR is a fancy laser pointer, essentially, that sprays out laser pulses – about 500,000 pulses per second – flying along at 23,000 feet, and measures how long it takes for the laser pulse to go out, hit the surface and come back, and we can use that information to then know the surface of the snow. Every square foot of mountain snow is touched by our lasers.
Dr. Evil You know, I have one simple request. And that is to have sharks with frickin' laser beams attached to their heads Now evidently my cycloptic colleague informs me that that cannot be done. Ah, what do I pay you people for, honestly Throw me a bone here
He said that he saw the laser sight on the shoulder, assumed it was the Taser, both the gun and the Taser have a laser sight, and he just made a mistake.
