Laser Design Inc. is a company headquartered in Minneapolis, MN that designs, manufactures, and sells 3D laser scanners used to digitally capture the shape of physical objects such as free-form surfaces and geometries.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
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] In 2015, Coherent purchased Raydiance, who made lasers used in automotive and medical manufacturing, for $9.3 million.
Most types of laser are an inherently pure source of light; they emit near-monochromatic light with a very well defined range of wavelengths.By careful design of the laser components, the purity of the laser light (measured as the "linewidth") can be improved more than the purity of any other light source.
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.
Smith & Wesson, Model 686 Plus equipped with Crimson Trace laser grip. Crimson Trace is an American manufacturer of laser sight equipment, chiefly but not exclusively for pistols. The firm specializes in in-line upper-grip-mounted red and green laser units, trigger-guard mounted sights, and training units.
Line laser with interchangeable lenses. A line laser is a device that employs a laser and an optical lens to project the laser beam as a line rather than a point (e.g. laser pointer). This may be achieved by passing the beam through a cylindrical lens or a Powell lens. [1]
Ray optics explanation (focused laser). In addition to keeping the bead in the center of the laser, a focused laser also keeps the bead in a fixed axial position: The momentum change of the focused rays causes a force towards the laser focus, both when the bead is in front (left image) or behind (right image) the laser focus.
