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. The small width of the beam and the low power of typical laser pointers make the beam itself invisible in a ...
Light level 5.0 μW/cm 2; for example, a legal 5 mW laser pointer at 1,200 feet (370 m). Simulation of temporary flash blindness where the image takes from a few seconds to a few minutes to fade away, depending on how much light entered the eye. Light level 50 μW/cm 2; for example, a legal 5 mW laser pointer at 350 feet (110 m).
Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.
Reports of lasers illegally pointed at aircraft in flight rose to a new high in 2023, ... Laser pointers, even those sold for less than $20 online, can distract pilots or cause flash blindness ...
A blue laser emits electromagnetic radiation with a wavelength between 400 and 500 nanometers, which the human eye sees in the visible spectrum as blue or violet. [1] Blue lasers can be produced by: direct, inorganic diode semiconductor lasers based on quantum wells of gallium (III) nitride at 380-417nm [2] [3] or indium gallium nitride at 450 ...

Buckeyes head football coach Ryan Day was once again the highest-paid Ohio State employee in 2023, taking home $9,173,463 in total compensation, according to university data as of Dec. 31.
Another military use of lasers is as a laser target designator. This is a low-power laser pointer used to indicate a target for a precision-guided munition, typically launched from an aircraft. The guided munition adjusts its flight-path to home in to the laser light reflected by the target, enabling a great precision in aiming.
