A laser lighting display or laser light show involves the use of laser light to entertain an audience. A laser light show may consist only of projected laser beams set to music , or may accompany another form of entertainment , typically musical performances.
The International Laser Display Association developed an image format suitable for interchanging image data between laser controllers and laser fixtures. The information may also be stored as frames, which can then be stored on a computer or other controlling device.
A projection keyboard is a form of computer input device whereby the image of a virtual keyboard is projected onto a surface: when a user touches the surface covered by an image of a key, the device records the corresponding keystroke. Some connect to Bluetooth devices, including many of the latest smartphone, tablet, and mini-PC devices with ...
Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
Box/Housing – a metal or plastic container to house the whole instrument and prevent light from spilling in unwanted directions. Light source . Lens or opening – the gap in the housing where the light is intended to come out. Reflector – behind or around the light source in such a way as to direct more light towards the lens or opening.
Laser color television (laser TV), or laser color video display, is a type of television that utilizes two or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display.

This used a laser to warm the storage media so that it became susceptible to magnetic fields and an electromagnet, similar to the one in a hard drive, to write data by realigning the material within. It worked like a conventional optical drive during reads, with the laser operating at lower energy levels, too low to heat the disk.
