Dryer was a filmmaker in the early 1970s. On one project, he worked with Dr. Elsa Garmire, a California Institute of Technology physicist interested in laser light art. . (She had previously worked with other artists on special event laser shows.) [1] Dryer was disappointed because the resulting film, LaserImage, [2] did not have the pure color and shimmer of laser l
LaserSoft Imaging became an early adopter of color- and image processing on the Macintosh. It was the first company to distribute video digitizers, such as Pixelogic's 'ProViz' and Truvel's 'TrueScan', the first professional color scanner for the Macintosh , which was first shown at Hannover trade fair CeBIT in 1988, to which LaserSoft Imaging ...
Model of a castle (0.2 mm x 0.3 mm x 0.4 mm) 3D-printed on a pencil tip via multiphoton lithography Multiphoton lithography (also known as direct laser lithography or direct laser writing) is similar to standard photolithography techniques; structuring is accomplished by illuminating negative-tone or positive-tone [jargon] photoresists via light of a well-defined wavelength.
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. [1]
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).
The needle-like object in the center of the image is the target holder, various instruments are pointed to image the explosions at its tip. The Shiva laser was a powerful 20-beam infrared neodymium glass (silica glass) laser built at Lawrence Livermore National Laboratory in 1977 for the study of inertial confinement fusion (ICF) and long-scale ...
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.
Sub-surface laser engraving is the process of engraving an image in a transparent solid material by focusing a laser below the surface to create small fractures. Such engraved materials are of high-grade optical quality (suitable for lenses, with low dispersion ) to minimize distortion of the beam.
