2. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   Laser cutting for metals has the advantage over plasma cutting of being more precise [11] and using less energy when cutting sheet metal; however, most industrial lasers cannot cut through the greater metal thickness that plasma can. Newer laser machines operating at higher power (6000 watts, as contrasted with early laser cutting machines ...

3. Laser beam machining - Wikipedia

   en.wikipedia.org/wiki/Laser_beam_machining

   Laser beam machining is best suited for brittle materials with low conductivity, but can be used on most materials. [2] Laser beam machining can be done on glass without melting the surface. With photosensitive glass, the laser alters the chemical structure of the glass allowing it to be selectively etched. The glass is also referred to as ...

4. Laser engraving - Wikipedia

   en.wikipedia.org/wiki/Laser_engraving

   Laser engraved glass microscope slide with the word "glass" engraved in 3pt font. Magnified to 40x and 100x A wine glass with a laser-engraved fill line. Stone and glass do not vaporise or melt easily. As a result, this makes them generally a better candidate for other means of engraving, most notably sandblasting or cutting using diamonds and ...

   Lasers are used in fiber-optic and free-space optical communications, optical disc drives, laser printers, barcode scanners, semiconductor chip manufacturing (photolithography, etching), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and ...

7. Bubblegram - Wikipedia

   en.wikipedia.org/wiki/Bubblegram

   A laser glass sculpture of a caffeine molecule. A bubblegram (also known as laser crystal, Subsurface Laser Engraving, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside.
