Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and ...
Diagram of a simple VCSEL structure. The vertical-cavity surface-emitting laser (VCSEL / ˈ v ɪ k s əl /) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also called in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.
The laser printer was invented at Xerox PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.
The VTech Laser 200 is an 8-bit home computer from 1983, also sold as the Salora Fellow (mainly in Fennoscandia, particularly Finland), the Seltron 200 in Hungary & Italy, the Smart-Alec Jr. by Dynasty Computer Corporation in Dallas, Texas for the USA, the Texet TX8000A ( United Kingdom), the Dick Smith VZ 200 (in Australia & New Zealand), and the VTech VZ 200 (in the United States & Canada).
The Arcadia was a cartridge-based projection light-gun system that allowed for two types of light-guns, the Arcadia Electronic Skeet Shoot Rifle, which was a single-shot only rifle with a pump reload and featured force feedback, a speaker for audio feedback, and a red-dot sight built into the front sight, as well as the Radar Pistol, which had ...
HP's own LaserJet was driven by a simple page description language, known as Printer Command Language, or PCL. The version for the LaserJet, PCL4, was adapted from earlier inkjet printers with the addition of downloadable bitmapped fonts. [4] It lacked the power and flexibility of PostScript until several upgrades provided some level of parity ...
The PUH is also known as a laser pickup, optical pickup, pickup, pickup assembly, laser assembly, laser optical assembly, optical pickup head/unit or optical assembly. [10] It usually consists of a semiconductor laser diode , a lens for focusing the laser beam, and photodiodes for detecting the light reflected from the disc's surface.
LosslessCut is a free, platform independent video editing software, which supports numerous audio, video and container formats. [4] [5]It is a graphical user interface, with MacOS, [6] Windows [7] and Linux [8] support, using the FFmpeg multimedia framework.
