  3. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    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.

    en.wikipedia.org/wiki/List_of_laser_applications

    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]

    en.wikipedia.org/wiki/Laser_engraving

    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.
