Home Dictionary Name: laserlaser disk
A digital data storage medium consisting of a thin disk onto which the data is impressed by a laser in the form of a linear sequence of dots same as optical disk The data is subsequently read back by the use of a laser beam See also compact disk...

laser printer
A printer controlled by a computer using a laser beam to produce images in a fine dot matrix pattern of charge on an electrostatic drum to which fine particles of ink are subsequently caused to adhere and the image of which is subsequently transferred to paper or another type of material in sheet form It is capable of high speed production of images with a higher resolution than those from dot matrix impact printers...

hologram
A photographic image giving the observer a seemingly three dimensional view of the represented object The three dimensional effect is produced by exposing a photographic recording medium to an interference pattern generated by a coherent beam of light as from a laser reflected from the subject interacting with a beam directly from the source The full three dimensional effect requires illumination of the image with coherent light but less perfect three dimensional visual effects may also be observed when the hologram is illuminated with white light...
