Lasers are tools, no more and no less. They are used to illuminate and to burn, to mark items and to measure them. In many ways, they are as ubiquitous as knives and tape measures, and they are treated as common consumer products in many ways. Yet their highly technical nature – consider the firm grasp of physics required to design them – means that lasers have a certain amount of mystery and wonderment surrounding them. That they can be used in products ranging from presentation pointers and home video projectors to industrial-scale hole drillers and semiconductors scribers adds...Read full article

    Glossary
    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    efficiency
    As applied to a device or machine, the ratio of total power input to the usable power output of the device.
    medical lasers
    Medical lasers are devices that produce intense beams of light with specific characteristics and properties, which are used for various medical applications. These lasers emit light in the form of coherent and focused beams, allowing precise control over the energy delivered to tissues. The term "laser" stands for "light amplification by stimulated emission of radiation." In the medical field, lasers are employed for diagnostic, therapeutic, and surgical purposes. Their applications...
    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
    power
    With respect to a lens, the reciprocal of its focal length. The term power, as applied to a telescope or microscope, often is used as an abbreviation for magnifying power.
    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
    wavelength
    Electromagnetic energy is transmitted in the form of a sinusoidal wave. The wavelength is the physical distance covered by one cycle of this wave; it is inversely proportional to frequency.
