A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
THOR (Tactical High-powered Operational Responder) is a US-developed short-range directed energy weapon (DEW) demonstrator targeted at disabling drone swarms. THOR is one of a series of directed energy countermeasures targeting small, cheap drones.
High power applications, such as hardening, cladding, and deep penetrating welding, require multiple kW of optical power, and are used in a broad range of industrial processes. Micro material processing is a category that includes all laser material processing applications under 1 kilowatt. [12]
Moderate and high-power lasers are potentially hazardous because they can burn the retina, or even the skin. To control the risk of injury, various specifications, for example 21 Code of Federal Regulations (CFR) Part 1040 in the US and IEC 60825 internationally
In the 2000s, Japanese manufacturers mastered the production of a blue laser with 60 mW of power and long lifetimes, making them applicable for devices that read a dense (due to blue's short wavelength) high-speed stream of data from Blu-ray, BD-R, and BD-RE.
Due to their thermal conductivity, pulsed, rather than continuous wave lasers, are preferred in laser engraving applications. High peak power, low pulse duration lasers are able to ablate material off a metal engraving surface without delivering enough energy to melt the surface. Laser on stainless steel.
