In late 2017, IPG announced the acquisition of Laser Depth Dynamics, a provider of an optical coherence tomography-based in-process quality monitoring and control solutions for laser-based welding applications. [29] The subsidiary operates as IPG Photonics (Canada) Inc. and is located in Kingston, Ontario. [30]
In 2006, Coherent acquired laser equipment manufacturer Excel Technology for $376 million. [9] Coherent purchased the German-based pulse laser company Lumera in 2012 for $52 million. [10] Their lasers were primarily used in micromachining in industrial processes that use lasers to add very slight amounts of heat. [10]
A coherent perfect absorber (CPA), or anti-laser, is a device which absorbs coherent waves, such as coherent light waves, and converts them into some form of internal energy, e.g. heat or electrical energy. [1] [2] It is the time-reversed counterpart of a laser. [3]
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.
OnTrac (formerly LaserShip) is a last-mile delivery company that services the continental United States. [1] [2] [3] [4] Founded in 1986 as LaserShip, the company is ...
A number of players (all diode laser based) were made that were capable of playing both sides of the disc automatically; at the end of the first side, or at the viewer's command, the machine would reverse the direction of the disc's rotation, simultaneously moving the laser pickup head to the other side of the disc, and then initiate playback.
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 ...
A laser turntable (or optical turntable) is a phonograph that plays standard LP records (and other gramophone records) using laser beams as the pickup instead of using a stylus as in conventional turntables. Although these turntables use laser pickups, the same as Compact Disc players, the signal remains in the analog realm and is never digitized.
