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 ...
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 ...

The use of lasers in Micro Materials Processing has found broad application in the development and manufacturing of screens for smartphones, tablet computers, and LED TVs. [13] A detailed list of industrial and commercial laser applications includes: Laser cutting. Laser welding.
Laser rangefinder. A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
