Laser printing is an electrostatic ... 1200 dpi printers have been widely available in the home market since 2008. 2400 dpi electrophotographic printing plate makers ...
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).
Xerography is a dry photocopying technique. [1] Originally called electrophotography, it was renamed xerography—from the Greek roots ξηρός xeros, meaning "dry" and -γραφία-graphia, meaning "writing"—to emphasize that unlike reproduction techniques then in use such as cyanotype, the process of xerography used no liquid chemicals.
An LED printer is a type of computer printer similar to a laser printer. Such a printer uses a light-emitting diode (LED) array as a light source in the printhead instead of the laser used in laser printers and, more generally, in the xerography process. The LED bar pulse-flashes across the entire page width and produces the image on the print ...
A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser originated as an acronym for light amplification by stimulated emission of radiation.
The laser works by the same principle as the maser, but produces higher-frequency coherent radiation at visible wavelengths. The maser was the precursor to the laser, inspiring theoretical work by Townes and Arthur Leonard Schawlow that led to the invention of the laser in 1960 by Theodore Maiman. When the coherent optical oscillator was first ...
A pregnant woman is recovering in the hospital after she was stabbed multiple times by a pizza delivery driver over the size of her tip, according to reports. The incident happened on Sunday, Dec ...
If the temperature of the laser is changed, then the index change of the DBR structure causes a shift in its peak reflective wavelength and thus the wavelength of the laser. The tuning range of such lasers is typically a few nanometres, up to a maximum of approximately 6 nm, as the laser temperature is changed over ~50 K. As a rule of thumb ...
